Oxide powder is the chemical compound solid powder contains one oxygen and another element, such as metal oxides, metal oxides are a chemical compound formed between metals, specifically cations such as Na, K, Li, etc., and oxygen. These compounds require at least of two elements, as compounds do, and always contain at least one oxygen, though there can be more than one. These formations tend to be solid, basic and are more dense than their nonmetallic oxide counterparts. Metal oxides typically contain an anion of oxygen in the oxidation state of −2. A great example is iron oxide, more commonly known as rust, it is the result of iron’s prolonged exposure to oxygen rich environments. metal oxides can be easily obtained in nature or reacting metal with acid. In order to get high purity metal oxide powder, nano-metallization is necessary.

Applications of Oxide Powder
Oxide powder and metal oxides are widely used in our daily life. Quicklime is a commonly used desiccant and can also be used for disinfection; iron oxide (Fe2O3), commonly known as iron red, can be used as a red pigment; some of the catalysts used in industrial processes are also metal oxides. Metal oxides are an important class of catalysts and have been widely used in the field of catalysis. After nano-metallization, the catalytic performance is better.

Nickel oxide is the main oxide of nickel. It is classified as an alkali metal oxide. Millions of kilograms of products with different qualities are produced every year, mainly as intermediates for nickel alloy production. The mineral form of NiO (arsenite) is very rare. The protection of other nickel(III) oxides, such as Ni2O3 and NiO2 is also claimed but has not been proven by X-ray crystallography.
Biomedicalmaterialsprogram is a trusted global Nickel Oxide NiO supplier. Feel free to send an inquiry about the latest Nickel Oxide price at any time. NiO adopts NaCl structure with octahedral Ni2+ and O2-positions. Conceptually simple structures are often called rock salt structures. Like many other binary metal oxides, NiO is usually not stoichiometric, which means that the Ni:O ratio deviates from 1:1. In nickel oxide, this non-stoichiometric NiO is accompanied by a color change. The stoichiometric correct NiO is green, and the non-stoichiometric NiO is black.

Performance of Nickel Oxide NiO Powder :
Nickel oxide is obtained by the action of nickel and oxygen at greater than 400℃, or by pyrolysis of nickel carbonate at 350℃. Used for making alloys, batteries, glass, enamel, ceramics, electronic components, nickel salts, and as a catalyst.


How is Nickel Oxide NiO produced?
NiO can be prepared by various methods. When heated to above 400°C, nickel powder reacts with oxygen to form NiO. In some commercial processes, green nickel oxide is made by heating a mixture of nickel powder and water at 1000°C. The reaction rate can be increased by adding NiO.
The simplest and most successful preparation method is to pyrolyze nickel (II) compounds (such as hydroxides, nitrates and carbonates) to produce a light green powder. By heating the metal in oxygen, the synthesis of the elements can produce gray to black powder, which indicates that the stoichiometry is wrong. It combines with sodium and potassium oxides at high temperatures (> 700°C) to form corresponding nickelates.
In addition, nickel oxide nanoparticles can be produced by thermally decomposing newly prepared nickel hydroxide through a sol-gel route at 300°C (572°F). X-ray diffractometer and vibrating sample magnetometer can be used to characterize the nickel oxide nanoparticles produced by this method.

Antimony Tin Oxide ATO Powder CAS 128221-48-7

About Antimony Tin Oxide ATO Powder:
Antimony tin oxide, also called antimony doped tin dioxide, antimony tin oxide, abbreviated as ATO. It is a non-resistive transparent conductive material in the semiconductor field. It can be used in various glass, plastics and various resins to play a role in transparency, conductivity, anti-static radiation, ultraviolet and infrared blocking. Tin oxide antimony conductive nanomaterials have broad application prospects in many fields due to their high conductivity and light color transparency. It is a new type of functional material that has developed rapidly in recent years.
 
Antimony tin oxide is a world-recognized excellent material with a series of unique properties. They show good electrical conductivity in antistatic applications and have good infrared absorption capabilities. Strong absorption of near-infrared light occurs, and transparency in the visible light range can be maintained in the film.
 
ATO (Antimony Tin Oxide) is a highly insoluble, thermally stable source of aluminum suitable for glass, optical and ceramic applications. Antimony tin oxide is one of the most commonly used transparent conductive oxides because it has two key properties, including optical transparency and conductivity. These characteristics are very important for photovoltaic devices including solar cells and flat-panel displays.
 
The current technology for forming particulate and nanoparticulate tin oxide and using an acidic medium to provide a surface coating, however, coating acid-sensitive materials with nanoparticulate antimony-doped tin oxide (ATO) films has become very important.
 
The antistatic coating is the main application market of nano ATO powder. Nano-composite transparent antistatic coatings can be prepared by adding nano-ATO powder as a conductive filler to the matrix resin (such as polyamide and acrylic) and selecting an appropriate dispersion method. Since the previous conductive fillers usually use carbon black, they are inferior to ATO powder in terms of color control. Feel free to send an inquiry to get the latest price if you would like to buy Antimony Tin Oxide ATO Powder in bulk.

Performance of Antimony Tin Oxide ATO Powder :
ATO, also known as antimony-doped tin dioxide, is mainly composed of tin oxide and antimony oxide. The particle size is mostly 5-80 nm.

How is Antimony Tin Oxide ATO Powder produced?
The chemical methods for preparing antimony tin oxide conductive nanomaterials mainly include precipitation method, hydrothermal synthesis method, sol-gel method, microemulsion method and so on.
The liquid phase co-precipitation method is the most commonly used and most mature method for preparing tin oxide antimony conductive nanomaterials. In this method, an aqueous solution is usually used as the reaction medium, a salt solution of tin and antimony is mixed, and sodium hydroxide or ammonia is added to the mixed solution. The precipitating agent and other precipitating agents precipitate the tin and antimony cations coexisting in the solution, and the precipitate is washed, dried and calcined to obtain the corresponding nanopowder.

Applications of Antimony Tin Oxide ATO Powder:

Adding nano-level ATO powder directly during fiber spinning, the key is the compatibility of inorganic nano-level ATO with fiber materials, and special dispersing additives need to be added;
Add nano-level ATO or textile auxiliaries in the dyeing process of raw materials (such as wool tops and polyester yarns) to complete dyeing and functionalization in one step;
Add nano-level ATO textile auxiliaries during the dyeing or finishing of grey fabrics.
Nano ATO powder has a small particle size, has good compatibility with plastics, and has a light color, which broadens the application of conductive powders on plastics. Conductive ATO can be made into plastic additives or plastic conductive masterbatch can be made into conductive plastic. If the ATO particles are large, they will have a certain negative impact on the production of conductive plastics. Therefore, ATO raw materials with the smallest possible particle size are required. Other applications of antimony tin oxide include:
1.Antimony tin oxide nanoparticles show excellent electrical and optical properties.
2.Antimony oxide can be used in the fields of optoelectronic display devices and flat panel display devices, such as LED, LCD and ECD.
3.Antimony oxide can also be used in solar cells and transparent electrodes.
4.The high conductivity of antimony oxide makes it suitable for use as an antistatic material in coatings, chemical fiber and polymer film industries.
5.The antimony tin oxide nanoparticles also show high heat resistance.
6.Antimony oxide can be used to shield the heat in buildings or glass and hot mirrors.
7.Antimony oxide can also be used in automobile glass and aircraft glass to prevent fog and frost.
8.Antimony tin oxide nanoparticles have the characteristics of reducing microwaves.
9.
Antimony oxide can be used in areas that need to be shielded from electromagnetic waves. These areas include computer rooms and radars.

How is Bismuth Oxide Bi2O3 powder produced?
1. Drop the sodium hydroxide solution without carbon dioxide into the bismuth nitrate solution (80 ~ 90 ℃) to make it mixed. During the precipitation process, the solution remains alkaline, and the white, bulky-expanding bismuth oxide hydrate Bi(OH)3 precipitates. The solution is heated, and after a short time of stirring, it dehydrates yellow bismuth trioxide. After water decanting washing, filtration and drying, bismuth oxide was prepared.
2. Add 1.5mol/L sodium hydroxide water solution without carbon dioxide to 0.1mol/L bismuth nitrate solution dissolved in 1mol/L nitric acid (at 80 ~ 90℃) in a nitrogen atmosphere to make them mixed. The solution remains alkaline during the precipitation process. Although the white and bulky-expanding bismuth oxide hydrate Bi(OH)3 precipitates, it dehydrates into light yellow bismuth trioxide after stirring in a hot solution for a while. The bismuth oxide was obtained by decanting and washing with water without air and carbon dioxide 15 times, then filtered and dried.
3. After the metal bismuth is loaded into the graphite crucible for melting, an arc is formed between the graphite electrode and the metal liquid surface under the flow of oxygen, and the metal is heated and oxidized. To ensure adequate oxygen supply, the crucible should be placed in a large container and continuously supplied with oxygen. The reaction temperature ranges from 750 ℃ to 800℃, and the purity of β-bismuth trioxide is more than 99.8%. After quenching the product in water or on a cold metal plate, the high-temperature phase β-type product is obtained.
4. Slowly add Bi(NO3)3·5H2O acidic solution (20g dissolved in 2mol/L HNO3) into excess sodium carbonate solution and stir vigorously.Bi2O3CO3 was precipitated, filtered, washed and dried.β-Bi2O3 was obtained by placing it in an aluminum boat and heating it in the air at 650K for about 1.5h
5. The basic bismuth nitrate is burned at 400 ~ 500℃, and the NO3- ion is removed about (3 ~ 4h) :
2BiONO3=Bi2O3+NO+NO2+O2
The finished product will turn lemon yellow after cooling.

6. Wash the surface of 16kg99.9% industrial bismuth with a small amount of dilute nitric acid, and then wash the surface with conductive water to remove nitric acid.

Aluminum Oxide Al2O3 CAS 1344-28-1

About Aluminium oxide:
Aluminum oxide is an electrical insulator, it has a fairly high thermal conductivity to ceramic materials. The most common form of crystalline alumina is called corundum. Alumina can provide activated, super-activated, acidic, alkaline and neutral grades, and has flash grades, TLC, biomass purification, decolorization, dioxin analysis, PCB removal, pyrogen removal and biotechnology wide-pore forms. Oxide does not conduct electricity. However, certain oxides of perovskite structures have conductivity in the cathodes of solid oxide fuel cells and oxygen generation systems. They are compounds containing at least one oxygen anion and one metal cation. They are generally insoluble in aqueous solutions (water) and are very stable, so they can be used in ceramic structures, such as clay bowls for the production of advanced electronic devices, and lightweight structural components used in aerospace and electrochemical applications, such as fuel cells. Exhibits ionic conductivity. Metal oxides are basic acid anhydrides, so they can react with acids and strong reducing agents in redox reactions. Reactive chromatography grade alumina is used in lighting, photographic chromatography and various chromatographic separation techniques. Alumina is usually available in most quantities immediately. High purity, sub-micron and nanopowder forms can be considered. Alumina can also be made into particles, pellets, powders, sputtering targets, tablets and nano-powders.

How is Aluminium oxide produced?
Aluminum oxide is produced by the bauxite process. The Bayer process is carried out in four steps. First, the bauxite is crushed, washed and dried, and then dissolved with caustic soda at high temperatures. Next, the mixture is filtered to remove impurities called "red mud" and discarded appropriately. The remaining alumina solution is transferred to a high tank called a settler. In the sedimentation tank, the hot solution begins to cool, and aluminum hydroxide seeds (very small particles) are added. The aluminum hydroxide seeds stimulate the precipitation of solid aluminum hydroxide crystals. Aluminum hydroxide precipitates at the bottom of the tank and is removed. Finally, all remaining caustic soda in the aluminum hydroxide is washed and heated to remove excess water. After this process, alumina (alumina) appears as a fine white powder. It looks a lot like sugar used in baking, but it is hard enough to scratch the glass plate.
 
Application of Aluminium oxide:
Most of the alumina produced is used to form aluminum metal. Oxygen usually reacts with metallic aluminum to catalyze corrosion. However, when combined with oxygen to form alumina, it forms a protective coating and prevents further oxidation. This increases the strength and makes the material less prone to deterioration. Alumina is mainly used as analytical reagents, dehydration of organic solvents, adsorbents, organic reaction catalysts, abrasives, polishing agents, raw materials for smelting aluminum, and refractory materials.
Industries that use alumina include:
Medical industry
Due to the hardness, biological inertness and chemical properties of alumina, it is used for hip replacement surgery prostheses, bionic implants, artificial eye substitutes, tissue reinforcement materials, crowns, abutments, bridges and other dental implants. The preferred material of the bearing. It is also used in laboratory equipment and tools such as crucibles, furnaces and other laboratory appliances.
Military and protective equipment
The strength and lightweight properties of alumina help to strengthen body armor, such as breastplates and armor for cars and airplanes, which is its largest market. Alumina is also used to synthesize sapphire bulletproof windows and bulletproof systems.
Electrical and electronic industry
Its high melting point and high boiling point, as well as its excellent heat resistance, make alumina an ideal material for high-temperature furnace insulators and electrical insulators. Alumina film is also a vital component in the microchip industry. Some of its other uses include spark plug insulators, micro-electric substrates and insulating heat sinks.

Performance of Aluminum Oxide Al2O3 Powder:
Aluminum oxide (aluminum oxide), chemical formula Al2O3. It is a high hardness compound with a melting point of 2054°C and a boiling point of 2980°C. It is an ion crystal that can be ionized at high temperatures and is commonly used in the manufacture of refractory materials. It is a white solid that is insoluble in water, odorless, tasteless, and extremely hard.

Zinc Oxide ZnO powder CAS 1314-23-4

About Zinc Oxide ZnO powder:
Zinc oxide is an inorganic substance, the chemical formula is ZnO. Insoluble in water, soluble in acids and strong bases.
Zinc oxide is a white powder or hexagonal crystal. Smells, tasteless and sand-free.It turns yellow when heated and turns white again when cooled. It sublimates when heated to 1800℃. The hiding power is half that of titanium dioxide and zinc sulfide. The tinting power is twice that of basic lead carbonate. Zinc oxide is soluble in acid, concentrated hydroxide base, ammonia water and ammonium salt solution, but insoluble in water and ethanol.
Zinc oxide is a famous white pigment, the common name is zinc white. It has the advantage of not being black in the presence of H2S gas because ZnS is also white. When heated, ZnO gradually changes from white and light yellow to lemon yellow, and when cooled, the yellow will recede.

Silicon Dioxide SiO2 powder CAS 7631-86-9

About Silicon Dioxide SiO2 powder:
Silica, also known as silicon dioxide, is a silicon oxide with the chemical formula SiO2. The most common form in nature is quartz and various organisms. In many parts of the world, silica is the main component of sand. Silica is one of the most complex and abundant material families, in the form of mixtures of various minerals and synthetic products. Notable examples include fused silica, fumed silica, silica gel and aerogel. It is used in structural materials, microelectronics (as electrical insulators), and components in the food and pharmaceutical industries.
 
Inhalation of finely divided crystalline silica is toxic and can cause severe inflammation of lung tissue, silicosis, bronchitis, lung cancer and systemic autoimmune diseases such as lupus and rheumatoid arthritis. High-dose inhalation of amorphous silica can cause non-permanent short-term inflammation, and all effects can be cured.
 
 Long-range arrangement of silicon and oxygen atoms forms crystalline silica, short-range arrangement or long-range disordered arrangement forms amorphous silica. In a silicon dioxide crystal, the silicon atoms are at the center of a regular tetrahedron, and the four oxygen atoms are at the four corners of the tetrahedron. Many tetrahedrons are held together by oxygen atoms at the four corners. Each oxygen atom is shared by two tetrahedrons, that is, each oxygen atom is bonded to two silicon atoms.
 
The simplest molecular formula for silica is SiO2, but SiO2 does not represent a simple molecule (just the ratio of the number of silicon atoms to the number of oxygen atoms in the crystal of silica). Pure natural silica crystal is a hard, fragile, insoluble, colorless and transparent solid, often used in the manufacture of optical instruments. Feel free to send an inquiry to get the latest price if you would like to buy Silicon Dioxide SiO2 powder in bulk.

How is Silicon Dioxide SiO2 powder produced?
Preparation method of amorphous silicon dioxide
The preparation of amorphous silica includes five steps, namely the preparation of silica gel, granulation process, sintering process, cleaning process and drying process.
1. Preparation of silica gel
Crushing silicon tetrachloride can produce silica gel, or pulverizing organic silicon compounds (such as tetra methoxy siloxane) to produce silica gel, or using fumed silica can produce high-quality silica gel.
2. Granulation process
By drying the silicone gel into a dry powder, pulverizing the dry powder, and then performing classification, a silica powder with a desired average yield can be obtained.
3. Sintering process
The silica powder obtained in the granulation process is sintered at a temperature of 800°C to 1450°C. The spheroidization process of thermal plasma is used to introduce argon gas at a predetermined flow rate and convert the output at a predetermined frequency to generate plasma. In the plasma torch, the sintered and obtained silica powder is dispersed at a predetermined feed rate, and heated and melted at a temperature of 2000 ℃ to the boiling point of silica.
4. Cleaning process
After the spheroidization step, the fine powder adhering to the surface of the spheroidized silica powder is removed.
5. Drying process
After the above cleaning process, the silica powder is dried.
 
Applications of Silicon Dioxide SiO2 powder:
Silica is a raw material for manufacturing glass, quartz glass, water glass, optical fiber, important parts of the electronics industry, optical instruments, handicrafts and refractory materials, and important material for scientific research.
 
1. Silica is the main ingredient in most glass production. When other minerals melt with silica, the freezing point reduction principle reduces the melting point of the mixture and increases the fluidity. The glass transition temperature of pure SiO 2 is about 1475K. When fused silica SiO2 cools quickly, it will not crystallize but will solidify into the glass. Therefore, most ceramic glazes are mainly composed of silica.
2. Silica can also be used as an additive, an excellent flow promoter, mainly used as a pressurizing agent, anti-sticking agent, and glidant.
3. Silica is particularly suitable for the granulation of oils and extracts, and it can also use glidants in direct compression.
4. As a disintegrant, silicon dioxide can greatly improve the fluidity of the granules, increase the bulk density, and increase the hardness of the prepared tablets. It can be used as an internal desiccant in the manufacture of granules to enhance the stability of the drug.
5. Silica can also be used as a filter aid, scavenger, defoamer, suspending agent and thickener for liquid preparations.
6. About 95% of the commercial uses of silica (sand) occur in the construction industry, such as the production of concrete (Portland cement concrete).
7. In cosmetics, silica plays a certain role due to its light diffusion properties and natural absorption.
8. The process of passivating the silicon surface by thermal oxidation (silicon dioxide) is critical to the semiconductor industry. It is usually used to manufacture metal oxide semiconductor field-effect transistors (MOSFET) and silicon integrated circuit chips (using planar technology).
9. Silica can be used for the extraction of DNA and RNA because it can bind to nucleic acids in the presence of chaotropic agents.
10. Since silicon dioxide is a natural oxide of silicon, compared with other semiconductors such as gallium arsenide or indium phosphide, silicon dioxide is more widely used.
11. Silicon dioxide can be grown on the surface of silicon semiconductors. The silicon oxide layer can protect the silicon surface during the diffusion process and can be used as a diffusion mask.


Storage Condition of Silicon Dioxide SiO2 powder :
Nano silicon dioxide SiO2 powder should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition should avoid the heavy pressure, according to ordinary goods transportation.

Oxide Powder

Indium Tin Oxide ITO Powder

About Indium Tin Oxide ITO Powder:
Indium tin oxide (ITO) is a ternary composition of different ratios of indium, tin and oxygen. According to the oxygen content, it can be described as ceramic or alloy. Usually encountered indium tin oxide as an oxygen-saturated composition, its formulation is 74% In, 18% O2 and 8% Sn by weight. Oxygen-saturated compositions are so typical that unsaturated compositions are referred to as oxygen-deficient ITO. The thin layer is transparent and colorless, and the bulk is a pale yellow to gray. In the infrared region of the spectrum, it acts like a metal mirror.
 
Indium tin oxide is one of the most widely used transparent conductive oxides because of its electrical conductivity and optical transparency and the ease with which it is deposited as a thin film. As with all transparent conductive films, a compromise must be made between conductivity and transparency, because increasing the thickness and increasing the concentration of charge carriers will increase the conductivity of the film, but will reduce its transparency.
 
Indium tin oxide films are most commonly deposited on the surface by physical vapor deposition. Usually, electron beam evaporation or a series of sputtering deposition techniques are used.
 
ITO is a mixed oxide of indium and tin. Depending on the composition, its melting point is in the range of 1526-1926°C. The composition of the most commonly used material is ca In4Sn. This material is an n-type semiconductor with a large bandgap of about 4 eV. ITO is transparent to visible light and has relatively high electrical conductivity. These features have great advantages in touch screen applications such as mobile phones. Feel free to send an inquiry to get the latest price if you would like to buy Indium Tin Oxide ITO Powder in bulk.

Performance of Indium Tin Oxide ITO Powder:

Chemically, ITO is the abbreviation of Indium Tin Oxides.
As a nano-indium tin metal oxide, it has good conductivity and transparency and can cut off harmful electronic radiation, ultraviolet rays and far-infrared rays. Therefore, indium tin oxide is usually sprayed on glass, plastic and electronic display screens, used as a transparent conductive film, while reducing harmful electronic radiation and ultraviolet and infrared.
In the oxide conductive film, the Sn-doped In2O3 (ITO) film has the highest transmittance and the best conductive performance, and it is easy to etch fine patterns in the acid solution, of which the light transmittance is more than 90%. The transmittance and resistance of ITO are controlled by the ratio of In2O3 and SnO2, usually SnO2:In2O3=1:9.

How is Indium Tin Oxide ITO Powder produced?
The ITO powder usually adopts the following preparation method: respectively oxidizing metal indium and metal tin to obtain indium oxide powder and tin oxide powder and then mixing and dispersing the indium oxide powder and tin oxide powder. In this method, it is difficult to completely synchronize the control conditions such as metal indium and metal tin as the basic raw material, such as the dissolution rate, dissolution temperature, neutralization pH value, neutralization temperature, and stirring speed, so the prepared indium oxide powder, The particle size deviation of tin oxide powder is large, which affects the quality of ITO film. In order to solve the problem of the uniformity of ITO powder, the co-precipitation method is also used to produce ITO powder. This method uses nitric acid to dissolve metal indium and metal tin, and then mix the resulting indium nitrate and tin nitrate according to the ratio, and then use ammonia to co-precipitate. Precipitation to obtain co-precipitated hydroxide, and finally, calcination to obtain indium tin oxide.
 
Applications of Indium Tin Oxide ITO Powder:
Indium tin oxide (ITO) is an optoelectronic material that has been widely used in research and industry. ITO can be used in many applications, such as flat panel displays, smart windows, polymer-based electronics, thin-film photovoltaic products, glass doors for supermarket freezers and architectural windows. Also, the ITO film used for the glass substrate helps the glass window to save energy.
 
The ITO green belt is used to produce electroluminescent, fully functional and fully flexible lamps. Besides, the ITO film is mainly used as an anti-reflective coating and is used in liquid crystal displays (LCD) and electroluminescence, where the film is used as a conductive transparent electrode.
 
ITO is commonly used to make transparent conductive coatings for displays (such as liquid crystal displays, OLED displays, plasma displays, touch panels, and electronic ink applications). ITO film is also used for organic light-emitting diodes, solar cells, antistatic coatings and EMI shielding. In organic light-emitting diodes, ITO is used as the anode (hole injection layer).
 
The ITO film deposited on the windshield is used to defrost the windshield of the aircraft. Heat is generated by applying a voltage to the film.
 
ITO is also used in various optical coatings, the most famous being infrared reflective coatings (hot mirrors) used in automobiles and sodium vapor lamp glass. Other uses include gas sensors, anti-reflective coatings, electrowetting on dielectrics, and Bragg reflectors for VCSEL lasers. ITO is also used as an infrared reflector for low emissivity window panes. Starting with the Kodak DCS 520, later Kodak DCS cameras also used ITO as a sensor coating to enhance the response of the blue channel.
 
ITO thin film strain gauges can operate at temperatures up to 1400°C and can be used in harsh environments such as gas turbines, jet engines and rocket engines.

Titanium Oxide TiO2 powder CAS 13464-67-7

About Titanium Oxide TiO2 powder:
Titanium Oxide TiO2 powder, also known as Titanium dioxide, is an important inorganic chemical pigment, mainly composed of Titanium dioxide. The titanium dioxide production process has a sulfuric acid method and chloride method of two process routes. It is widely used in coating, printing ink, paper making, plastic and rubber, chemical fiber, ceramics and other industries.
 
Among the commonly used white pigments, the relative density of titanium dioxide is the smallest, and the same mass of white pigments, titanium dioxide has the largest surface area and the highest pigment volume. The chemical properties of titanium dioxide are very stable, are a kind of acidic amphoteric oxide. Almost no reaction with other elements and compounds at room temperature, on oxygen, ammonia, nitrogen, hydrogen sulfide, carbon dioxide, sulfur dioxide are not effective, insoluble in water, fat, dilute acid and inorganic acid, alkali, only soluble in hydrofluoric acid. But under the action of light, titanium dioxide can take place a continuous REDOX reaction, has the photochemical activity. This kind of photochemical activity, under ultraviolet radiation anatase type titanium dioxide, is particularly obvious, this property makes titanium dioxide is some inorganic compounds of the photosensitive oxidation catalyst and some organic compounds of photosensitive reduction catalyst.
 
Titanium dioxide has Rutile type (Rutile R type) and Anatase type (A-type) two kinds of structure, Rutile crystal structure is dense, relatively stable, small optical activity, so good weather resistance, at the same time has A higher hiding power, color extinction. Titanium dioxide has semiconductor properties, its electrical conductivity increases rapidly with temperature, and it is also very sensitive to hypoxia. The dielectric constant and semiconductor properties of rutile TiO 2 are very important to the electronic industry, which can be used to produce electronic components such as ceramic capacitors.
 
According to Mos hardness scale of 10 points, rutile TiO2 is 6 ~ 6.5, anatase TiO2 is 5.5 ~ 6.0, so in chemical fiber extinction in order to avoid wear spinneret hole and use anatase. Although titanium dioxide has hydrophilic, its hygroscopicity is not too strong, rutile type is smaller than the anatase type. The hygroscopicity of titanium dioxide has a certain relationship with the size of its surface area, large surface area, high hygroscopicity, but also related to the surface treatment and properties. Feel free to send an inquiry to get the latest price if you would like to buy Titanium Oxide TiO2 powder in bulk.

How is Titanium Oxide TiO2 powder produced?
Titanium dioxide was manufactured in two different ways: Sulphate Process and Chloride Process.
1.Sulphate Process

Titanium sulfate is produced by acidolysis of iron titanium powder and concentrated sulfuric acid. The concentrated sulfuric acid is decomposed into metantitanic acid, which is then calcined and crushed to obtain titanium dioxide products. This method can produce anatase type and rutile type titanium dioxide. The sulfuric acid method has the advantages of low price and easy to get ilmenite and sulfuric acid as raw materials, more mature technology, simple equipment, easy to solve anti-corrosion materials. Its disadvantage is that the process is long, can only be based on intermittent operation, wet method operation, high consumption of sulfuric acid, water, waste and by-products, large pollution to the environment.
2.Chloride Process
The chlorination method is to use titanium-containing raw materials, high titanium chloride slag, or artificial rutile, or natural rutile and chlorine gas reaction to produce titanium tetrachloride, distillation, and then gas-phase oxidation; After rapid cooling, TiO2 was obtained by gas-solid separation. The TiO2 adsorption due to a certain amount of chlorine needs to be heated or steam treatment to remove it. The process is simple, but at 1000℃ or higher conditions of chlorination, there are many chemical engineering problems such as chlorine, chlorine oxide, titanium tetrachloride high corrosion need to be solved, coupled with the special raw materials used, compared with the sulfuric acid method cost. Chlorination process production is continuous production, the production equipment operation flexibility is not large, but its continuous process production, the process is simple, fewer process control points, product quality is easy to achieve the optimal control. The advantages of the chlorination method are short process, easy expansion of production capacity, a high degree of continuous automation, relatively low energy consumption, and high-quality products can be obtained. Its disadvantages are a large investment, complex equipment structure, high material requirements, high-temperature resistance, corrosion resistance, device maintenance is difficult, research and development is difficult.

Application of Titanium Oxide TiO2 powder:
The most important applications of titanium dioxide are paints, varnishes and paper and plastics, which account for about 80 percent of world consumption of titanium dioxide. Other pigment applications, such as printing inks, fibers, rubber, cosmetics and food, account for another 8%. The rest is used for other applications, such as industrial pure titanium, glass and glass-ceramics, electroceramics, metallic copper, catalysts, electrical conductors and chemical intermediates.
1. Titanium dioxide is the most widely used white pigment because of its brightness and high refractive index.
2. Titanium dioxide is also an effective sunscreen in powder form, where it is used as a pigment to provide whiteness and opacity to products such as paints, coatings, plastics, paper, inks, food products, pharmaceuticals (such as tablets and tablets) and most toothpaste. In painting, it is often abbreviated as "vivid white", "perfectly white", "whitest white" or other similar terms.
3. Titanium dioxide in the rubber industry as a colorant, but also with reinforcing, anti-aging, filling the role.
4. In white and color rubber products to add titanium dioxide, under sunlight, sun resistance, no cracking, no discoloration, stretching rate and acid and alkali resistance.
5. Titanium dioxide for rubber, mainly used for automobile tires, rubber shoes, rubber floor, gloves, sports equipment, etc., generally anatase type.
6. For automobile tire production, often add a certain amount of rutile titanium dioxide products, to enhance the ability to resist ozone and ultraviolet.
7. Titanium dioxide is also widely used in cosmetics. Because titanium dioxide is non-toxic, far superior to lead white, almost all kinds of powdered titanium dioxide replace lead and zinc white.
8. Only 5%-8% of titanium dioxide powder can be added to the permanent white so that the spice is more slippery, adhesion, absorption and hiding power.
9. Titanium dioxide in gouache and cold cream can reduce the greasy and transparent feeling.
10. Titanium dioxide can also be used in a variety of other spices, sunscreen, soap, white soap and toothpaste.
11. When deposited as a thin film, the refractive index and color of titanium dioxide make it an excellent reflective optical coating for dielectric mirrors.
12. Some grades of modified titanium-based pigments used in sparkling paints, plastics, topcoats and cosmetics - these are artificial pigments whose particles have two or more layers of various oxides (usually titanium dioxide, iron oxide or alumina) to produce a shimmer, iridoid and/or pearlescent effect.
13. Titanium dioxide is used as a pigment, sunscreen and thickener in cosmetics and skincare products in sunscreen and UV protection pigments.
14. As a sunscreen, ultrafine TiO 2 is used, which is notable for its combination with ultrafine zinc oxide and is considered to be an effective sunscreen that reduces the incidence of sunburn and minimizes premature photoaging, photocarcinogenesis and immunosuppressive sun exposure associated with long-term excess. Sometimes these UV-blockers are used in combination with iron oxide pigments in sunscreens to increase protection against visible light.

Zirconium Oxide ZrO2 powder CAS 1314-23-4

About Zirconium Oxide ZrO2 powder:
Zirconium oxide (ZrO2), sometimes known as zirconia (not to be confused with zircon), is a white crystalline oxide of zirconium. Its most naturally occurring form, with a monoclinic crystalline structure, is the mineral baddeleyite. A dopant stabilized cubic structured zirconia, cubic zirconia, is synthesized in various colors for use as a gemstone and a diamond simulant. Our company also can supply zirconium oxide ceramic(zro2 ceramic) products

If you want to know zirconium oxide price, please send inqury to sales1@rboschco.


Zirconium oxide is chemically unreactive. It is slowly attacked by concentrated hydrofluoric acid and sulfuric acid. When heated with carbon, it converts to zirconium carbide. When heated with carbon in the presence of chlorine, it converts to zirconium tetrachloride.
Zirconium dioxide is one of the most studied ceramic materials. ZrO2 adopts a monoclinic crystal structure at room temperature and transitions to tetragonal and cubic at higher temperatures. The change of volume caused by the structure transitions from tetragonal to monoclinic to cubic induces large stresses, causing it to crack upon cooling from high temperatures.

Three phases are known: monoclinic below 1170 °C, tetragonal between 1170 °C and 2370 °C, and cubic above 2370 °C. The trend is for higher symmetry at higher temperatures, as is usually the case. A small percentage of the oxides of calcium or yttrium stabilize in the cubic phase. The very rare mineral tazheranite, (Zr, Ti, Ca)O2, is cubic. Unlike TiO2, which features six-coordinated titanium in all phases, monoclinic zirconia consists of seven-coordinated zirconium centers. This difference is attributed to the larger size of the zirconium atom relative to the titanium atom.

The ZrO2 band gap is dependent on the phase (cubic, tetragonal, monoclinic, or amorphous) and preparation methods, with typical estimates from 5–7 eV. A special case of zirconia is that of tetragonal zirconia polycrystal, or TZP, which is indicative of polycrystalline zirconia composed of only the metastable tetragonal phase. Feel free to send an inquiry to get the latest price if you would like to buy Zirconium Oxide ZrO2 powder in bulk.

Performance of Zirconium Oxide ZrO2 powder :
The chemical property of zirconium dioxide is inactive, and has the properties of high melting point, high resistivity, high refractive index and low coefficient of thermal expansion, making it an important high temperature resistant material, ceramic insulating material and ceramic sunscreen, and it is also the main part of artificial drills. raw material. The band gap is about 5-7eV.

How is Zirconium Oxide ZrO2 powder produced?
The industrial refractory material is fully stabilized zirconia, and most of the electric mete is made. Carbon and stabilizable calcium oxide were added to the zircon meter fuse, and the zirconia and calcium oxide was used to generate a solid solution, and then stably zirconia was produced while the zirconia and the calcium oxide was used to form a solid solution. Stable and partially stabilized zirconia used in fine ceramics is generally prepared with wet.

The most mature and commonly used is neutralization. The purified chloride zirconium is dissolved with pure water, filtrate the insoluble matter, adjust the zirconium concentration in the solution, and add the required amount of a cerium chloride solution (or other rare earth metal or alkaline chloride solution), add ammonia water Medium and precipitation. The precipitate was washed with hot water and then filtered, dried and calcined. Ultrafine stabilized zirconia powder can be obtained by treating the calcined product.
Partially stabilized zirconia is to control the amount of added stabilizer, which is not sufficient to achieve complete stability. Partially yttria zirconia has high strength and thermal shock resistance, and there is a relatively wide application in structural ceramics.
 
Applications of Zirconium Oxide ZrO2 powder:
For metal zirconium and zirconium compounds, fire bricks and crucibles, high-frequency ceramics, abrasive materials, ceramic pigments and zirconates are mainly used for piezoelectric ceramic products, daily ceramics, refractory materials and precious metals smelting Zirconium brick, zirconium tube, the crucible, etc.

Refractory
Zirconia fibers are polycrystalline refractory fiber material. Due to the high melting point of the ZrO2 substance itself, the non-oxidation and other high-temperature excellent characteristics, the ZrO2 fiber has higher use temperatures than other refractory fibers such as alumina fibers, mullite fibers, aluminum silicate fibers. The zirconia fiber is used for a long time in a super high-temperature oxidation atmosphere above 1500 ° C, and the highest temperature is as high as 2200 ° C, and even 2500 ° C can maintain a complete fiber shape, which is currently the top top of the topic. Fiber material.

Gas turbine
The application of plasma spray
zirconium oxide thermal barrier coating on-air and industrial gas turbines has great progress, which has been used for turbine portions of gas turbines within a certain limit. Since this coating can reduce the temperature of 50 to 200 ° C of the air-cooled high-temperature member, the durability of the high-temperature member can significantly improve the durability of the high-temperature member, or improve the temperature of the gas temperature or reduce the amount of temperature required to maintain the high-temperature member. Change, thereby increasing the efficiency of the engine.


Ceramic material
Since the refractive index of zirconia is large, the melting point is high, the corrosion resistance is strong, so it is used in the kiln industry. Piezoelectric ceramic products include filters, speakers ultrasonic water detectors, and the like. There are also daily use ceramics (industrial ceramic glaze), zircon tiles and zirconium tubes for precious metal smelting. Nano-grade zirconia can also be used as a polishing agent, abrasive, piezoelectric ceramic, precision ceramic, ceramic glaze and high-temperature pigment matrix material.
