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. It is foreseeable that nano-metal oxides will be an important direction for catalyst development.

Iron Oxide Fe2O3 CAS 1309-37-1

About Iron Oxide Fe2O3 Powder:
Iron (III) oxide or iron oxide is an inorganic compound with the molecular formula Fe2O3. It is one of the three main oxides of iron, and the other two are rare forms of iron oxide (II) and natural magnetite iron oxide (II, III).
 
Iron oxide or iron trioxide with the general formula Fe2O3 is an inorganic compound known to be one of the three main oxides of iron naturally present in a mineral called magnetite. When iron oxide is used as a suspension in solutions and applications in the fields of biomedicine, agriculture and the environment, it has unique super magnetic properties and easy separation methods. The advantage of iron oxide powder is that it can be modified with a variety of inorganic and organic compounds (such as starch, polyelectrolyte and non-ionic detergent) according to its main surface chemical potential so that it can be used for more applications. Iron oxide is considered to be the most common magnetic particle and powder used in biomedical applications by applying an external magnetic field.
 
Iron oxide is a compound with ferromagnetic properties. When placed in an external magnetic field, the compound is magnetic. When they are obtained in a controlled size and crystal morphology, this property proves to be the desired characteristic. Iron oxide fine particles have become the focus of attention due to their low toxicity, magnetic properties, and convenient separation methods in medical diagnosis and magnetic resonance imaging (MRI). The application of iron oxide on the macro scale and its reactivity are decisive factors, but when available in smaller sizes in the micron and nano scales, they exhibit spontaneous combustion. As a semiconductor material, iron oxide has negative temperature efficiency of resistance. Feel free to send an inquiry to get the latest price if you would like to buy Iron Oxide Fe2O3 Powder in bulk.

How is Iron Oxide Fe2O3 Powder produced?
There are wet and dry methods for preparing Iron Oxide Fe2O3. Wet-process products have fine crystals, soft particles, easy to grind, and easy to use as pigments. Dry-process products have large crystals and hard particles, which are suitable for magnetic materials, polishing and abrasive materials.
1. Wet method
Quickly react a certain amount of 5% ferrous sulfate solution with excess sodium hydroxide solution (the alkali excess is required to be 0.040.08g/mL), and pass in the air at room temperature to make it all become reddish-brown ferric hydroxide colloidal solution, As the nucleus of deposited iron oxide. Take the crystal nucleus as the carrier, use ferrous sulfate as the medium, and pass in the air. At 7585℃, in the presence of metallic iron, the ferrous sulfate reacts with oxygen in the air to form iron oxide (ie iron red) and deposits on the crystal nucleus, The sulfate radicals in the solution reacts with the metallic iron to regenerate ferrous sulfate, and the ferrous sulfate is oxidized to iron red by air to continue to deposit so that the circulation to the end of the whole process will generate red iron oxide.
2. Dry method
Nitric acid reacts with iron to form ferrous nitrate, which is cooled and crystallized, dehydrated and dried, then ground and calcined at 600-700°C for 8-10 hours, washed with water, dried, and pulverized to obtain iron oxide red product. Iron oxide yellow can also be used as a raw material to obtain red iron oxide after calcination at 600700℃.
 
Applications of Iron Oxide Fe2O3 Powder:
1. Iron industry
The overwhelming application of iron(III) oxide is as the feedstock of the steel and iron industries, e.g. the production of iron, steel, and many alloys.
2. Polishing
A very fine powder of ferric oxide is known as "jeweler's rouge", "red rouge", or simply rouge. It is used to put the final polish on metallic jewelry and lenses, and historically as a cosmetic. Rouge cuts more slowly than some modern polishes, such as cerium(IV) oxide, but is still used in optics fabrication and by jewelers, for the superior finish it can produce. When polishing gold, the rouge slightly stains the gold, which contributes to the appearance of the finished piece. Rouge is sold as a powder, paste, laced on polishing cloths, or solid bar (with a wax or grease binder). Other polishing compounds are also often called "rouge", even when they do not contain iron oxide. Jewelers remove the residual rouge on jewelry by use of ultrasonic cleaning. Products sold as "stropping compounds" are often applied to a leather strop to assist in getting a razor edge on knives, straight razors, or any other edged tool.
3. Pigment
Two different colors at different hydrate phases (α = red, β = yellow) of iron(III) oxide hydrate; they are useful as pigments.
Iron(III) oxide is also used as a pigment, under the names "Pigment Brown 6", "Pigment Brown 7", and "Pigment Red 101". Some of them, e.g. Pigment Red 101 and Pigment Brown 6, are approved by the US Food and Drug Administration (FDA) for use in cosmetics. Iron oxides are used as pigments in dental composites alongside titanium oxides. Hematite is the characteristic component of the Swedish paint color Falu red.
4. Magnetic recording
Iron(III) oxide was the most common magnetic particle used in all types of magnetic storage and recording media, including magnetic disks (for data storage) and magnetic tape (used in audio and video recording as well as data storage). Its use in computer disks was superseded by cobalt alloy, enabling thinner magnetic films with higher storage density.
5. Photocatalysis
α-Fe2O3 has been studied as a photoanode for solar water oxidation. However, its efficacy is limited by a short diffusion length (2-4 nm) of photo-excited charge carriers and subsequent fast recombination, requiring a large overpotential to drive the reaction. Research has been focused on improving the water oxidation performance of Fe2O3 using nanostructuring, surface functionalization, or by employing alternate crystal phases such as β-Fe2O3.
6. Medicine
Calamine lotion, used to treat mild itchiness, is chiefly composed of a combination of zinc oxide, acting as astringent, and about 0.5% iron(III) oxide, the product's active ingredient, acting as an antipruritic. The red color of iron(III) oxide is also mainly responsible for the lotion's pink color.

Tungsten Oxide WO3 Powder CAS 1314-35-8

About Tungsten Oxide WO3 Powder:
Tungsten trioxide is an inorganic substance with the chemical formula WO3, yellow powder. It is obtained by adding acid after the fusion of ore and soda ash.
Tungsten trioxide is a light yellow orthorhombic crystalline powder. The color changes from lighter to darker when heated. The specific gravity is 7.16 g/cm3, the melting point is 1473°C, and the boiling point is 1750°C. It sublimates significantly at 850°C and turns green when melted. It is stable in the air, insoluble in water and inorganic acids except for hydrofluoric acid, and can be slowly dissolved in ammonia water and concentrated sodium hydroxide solution.
 
Tungsten(VI) oxide, also known as tungsten trioxide or tungstic anhydride, WO3, is a chemical compound containing oxygen and the transition metal tungsten. It is obtained as an intermediate in the recovery of tungsten from its minerals.  Tungsten ores are treated with alkalis to produce WO3. Further reaction with carbon or hydrogen gas reduces tungsten trioxide to pure metal.
 
Tungsten(VI) oxide occurs naturally in the form of hydrates, which include minerals: tungstite WO3·H2O, meymacite WO3·2H2O and hydrotungstite (of the same composition as meymacite, however sometimes written as H2WO4). These minerals are rare to very rare secondary tungsten minerals.
 
The crystal structure of tungsten trioxide is temperature-dependent. It is tetragonal at temperatures above 740 °C, orthorhombic from 330 to 740 °C, monoclinic from 17 to 330 °C, triclinic from -50 to 17 °C, and monoclinic again at temperatures below -50 °C. The most common structure of WO3 is monoclinic with space group P21/n.
 
Tungsten trioxide is a strong oxidizing agent: it reacts with rare-earth elements, iron, copper, aluminum, manganese, zinc, chromium, molybdenum, carbon, hydrogen and silver, being reduced to a pure tungsten metal. Reaction with gold and platinum reduces it to dioxide. Feel free to send an inquiry to get the latest price if you would like to buy Tungsten Oxide WO3 Powder in bulk.

How is Tungsten Oxide WO3 Powder produced?
Tungsten trioxide can be prepared in several different ways. CaWO4, or scheelite, is allowed to react with HCl to produce tungstic acid, which decomposes to WO3 and water at high temperatures.
CaWO4 + 2 HCl → CaCl2 + H2WO4
H2WO4 → H2O + WO3
 
Another common way to synthesize WO3 is by calcination of ammonium para tungstate (APT) under oxidizing conditions:
(NH4)10[H2W12O42] • 4H2O → 12 WO3 + 10 NH3 + 10 H2O
 
Applications of Tungsten Oxide WO3 Powder:

Manganese Dioxide MnO2 CAS 1313-13-9

About Manganese Dioxide MnO2:
Manganese dioxide is an inorganic compound with the chemical formula MnO2, which exists in the form of pyrolusite in nature. Physical properties: black amorphous powder, or black orthorhombic crystals. Solubility: hardly soluble in water, weak acid, weak base, nitric acid, cold sulfuric acid, pulverize concentrated hydrochloric acid under heating to produce chlorine.


If you want to know manganese dioxide price/MnO2 price/manganese oxide price, please send inquiry to sales1@rboschco.com

 
MnO2 is an alpha polymorph that can incorporate various atoms (and water molecules) in the "tunnels" or "channels" between the manganese oxide octahedrons. People are very interested in α-MnO2 as a possible cathode for lithium-ion batteries.
 
Manganese dioxide is an amphoteric oxide. It is a very stable black powdery solid at room temperature and can be used as a depolarizer for dry batteries. It is often used in the laboratory to produce chlorine by its oxidizing property and the action of concentrated HCl. Manganese dioxide is a strong oxidant in acidic media. Manganese dioxide is an [MnO₂] octahedron. The oxygen atom is on the top of the octahedron, and the manganese atom is in the octahedron. [MnO₂] octahedrons are connected together to form a single or double chain. These chains and other chains co-top to form The tunnel structure of voids, octahedrons or hexagonal close-packed, or square close-packed.

Manganese 2 oxide is an amphoteric oxide, and there is a corresponding salt in the form of a perovskite structure such as BaMnO3 or SrMnO3 (obtained by a compound reaction in a molten alkali system), and manganese tetrachloride is also present.
 
When electrolytic manganese dioxide encounters a reducing agent, it is oxidizing. For example, manganese dioxide is heated in a stream of hydrogen to 1400K to obtain manganese oxide; manganese dioxide is heated in a stream of ammonia to obtain brown-black manganese trioxide; the manganese dioxide is reacted with concentrated hydrochloric acid to obtain l chlorine Manganese, chlorine and water.

When manganese dioxide encounters strong oxidants, it also exhibits reducibility. If manganese dioxide, potassium carbonate and potassium nitrate or potassium chlorate are mixed and melted, a dark green melt can be obtained, and the melt can be dissolved in water and cooled to obtain potassium manganate, a compound of hexavalent manganese.

Manganese dioxide is a strong oxidant in acidic media. It is used as a catalyst in the decomposition of potassium chlorate [KClO3] and the decomposition of hydrogen peroxide (hydrogen peroxide, H2O2).

Due to the strong oxidant, manganese dioxide does not burn by itself, but it supports combustion and should not be placed with flammable materials. Feel free to send an inquiry to get the latest price if you would like to buy Manganese Dioxide MnO2 in bulk.

Product Performance of Manganese Dioxide MnO2 CAS 1313-13-9:
Physical properties: black amorphous powder, or black rhombic crystals. Solubility: Difficult to dissolve in water, weak acid, weak base, nitric acid, cold sulfuric acid, and dissolve in concentrated hydrochloric acid under heating to produce chlorine gas.

How is Manganese Dioxide MnO2 produced?
Naturally occurring manganese dioxide contains impurities and a large amount of manganese trioxide. Only a limited number of deposits contain gamma modifiers of sufficient purity to meet the needs of the battery industry.

The production of batteries and ferrites (the two main uses of manganese dioxide) requires high-purity manganese dioxide. The battery needs "electrolytic manganese dioxide", and the ferrite needs "chemical manganese dioxide".
1. Chemical Manganese Dioxide
One method is to start with natural manganese dioxide and then use dinitrogen tetroxide and water to convert it into a solution of manganese (II) nitrate. The evaporation of water leaves crystallized nitrates. At a temperature of 400°C, the salt decomposes, releasing N2O4 and leaving a pure manganese dioxide residue. These two steps can be summarized as:
MnO2 +N2O4⇌MnNO32

2. Carbothermal reduction of manganese dioxide
In another method, manganese dioxide is carbothermal reduced to manganese (II) oxide dissolved in sulfuric acid. The filtered solution was treated with ammonium carbonate to precipitate MnCO.
The carbonate is calcined in air to obtain a mixture of manganese (II) and manganese (IV) oxides. To complete the process, the suspension of the material in sulfuric acid is treated with sodium chlorate. The chloric acid formed in situ can convert any Mn(III) and Mn(II) oxides into carbon dioxide, releasing chlorine by-products.

3. Manganese epoxide and manganese monoxide
The third method involves manganese epoxide and manganese monoxide. The two reagents are mixed in a ratio of 1:3 to form manganese dioxide:
Mn2O7 + 3 MnO→5 MnO2
Finally, the effect of potassium permanganate on manganese sulfate crystals produces the desired oxide.
2 KMnO4 + 3 MnSO4 + 2 H2O→5 MnO2 + K2SO4 + 2 H2SO4

4. Electrolytic Manganese Dioxide
Electrolytic manganese dioxide (EMD) is used in zinc-carbon batteries together with zinc chloride and ammonium chloride. EMD has also commonly used in manganese zinc dioxide rechargeable alkaline (Zn RAM) batteries. For these applications, purity is critical. The production method of EMD is similar to the production method of electrolytic ductile pitch (ETP) copper: manganese dioxide is dissolved in sulfuric acid (sometimes mixed with manganese sulfate) and electricity is applied between the two electrodes. The dissolved MnO2 enters the solution in the form of sulfate and is deposited on the anode.

Applications of Manganese Dioxide MnO2:
Manganese dioxide is a black or brown solid, naturally present in the mineral pyrolusite, which is the main ore of manganese and manganese nodules.

The main use of MnO2 is for dry batteries, such as alkaline batteries and zinc-carbon batteries.

MnO2 is also used as a precursor for pigments and other manganese compounds (such as KMnO4). It is used as a reagent in organic synthesis, for example for the oxidation of allyl alcohol.

MnO2 is used as a depolarizer for dry batteries, as a catalyst and oxidant in the synthesis industry, and as a colorant, decolorant and iron removal agent in the glass industry and enamel industry.

MnO2 is used to manufacture metallic manganese, special alloys, ferromanganese castings, gas masks and ferrites for electronic materials.

MnO2 can be used in the rubber industry to increase the viscosity of rubber.

MnO2 is used as a catalyst in chemical experiments

Used as a catalyst for the decomposition of hydrogen peroxide (hydrogen peroxide) to produce oxygen.

Used as a catalyst when heating potassium chlorate to decompose and produce oxygen.

It reacts with elemental aluminum powder to produce manganese by a thermite reaction.

Use pigments, yellow glass, etc.

React with hot concentrated hydrochloric acid to produce chlorine.

It reacts with molten caustic potassium (potassium hydroxide) in the air to produce potassium manganate.

In the decomposition reaction of potassium permanganate, manganese dioxide acts as a self-catalyst for potassium permanganate.

Storage Condition of Manganese Dioxide MnO2 Powder:
Precautions for storage: Store in a cool, ventilated warehouse. Keep away from fire and heat. It should be stored separately from combustibles (combustibles), reducing agents and acids, and avoid mixed storage. The storage area should be equipped with suitable materials to contain the leakage.

Iron Oxide Fe3O4 Powder CAS 1317-61-9

About Iron Oxide Fe3O4 Powder
Iron oxide (II, III) (Fe3O4) is a highly insoluble and thermally stable iron source suitable for glass, optical and ceramic applications. Oxide does not conduct electricity. However, certain oxides of perovskite structure 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, making them useful for ceramic structures, as simple as the production of clay bowls for advanced electronic devices, and for lightweight structural components in aerospace and electrochemical applications such as fuels Batteries in which they exhibit ionic conductivity. Metal oxides are basic high-purity (99.999%) iron oxide (FeO) anhydrides, so they can react with acids and strong reducing agents in redox reactions. Iron oxide can also be made into particles, nuggets, powders, sputtering targets, tablets, and Nanopowders. In most cases, iron oxide is usually available immediately.

Copper Oxide CuO powder CAS 1317-38-0

 About Cuprous Oxide CuO powder: 
Copper oxide is an inorganic substance with the chemical formula CuO. It is a black oxide of copper, slightly amphiphilic, slightly hygroscopic.
Copper oxide Virtually insoluble in water or alcohols; copper oxide dissolves slowly in ammonia solution but quickly in ammonium carbonate solution; it is dissolved by alkali metal cyanides and by strong acid solutions; hot formic acid and boiling acetic acid solutions readily dissolve the oxide.
Copper oxide is mainly used to make rayon, ceramics, glaze and enamel, batteries, petroleum desulfurizes, pesticides, and also for hydrogen production, catalysts, and green glass.
Cuprous oxide CuO is produced on a large scale by pyrometallurgy, which is a stage of extracting copper from ore. The ore is treated with an aqueous mixture of ammonium carbonate, ammonia and oxygen to obtain copper (I) and copper (II) amino complexes, which are extracted from the solid. These complexes are decomposed with steam to produce CuO.
Cupric oxide is used as a precursor in many copper-containing products such as wood preservatives and ceramics. The mean daily dietary intake of copper in adults ranges between 0.9 and 2.2 mg. Common routes of cupric oxide exposure include ingestion, dermal exposure and inhalation. Copper(II) oxide nanoparticles ( NPCuO) have industrial applications as antimicrobial agents in textiles and paints and catalysts in organic synthesis. They may also be produced from electronic wastes. Cupric oxide poses potential health and environmental concerns due to toxic and muta particles generating reactive oxygen species. Feel free to send an inquiry to get the latest price if you would like to buy Cuprous Oxide CuO powder in bulk.


Performance of Copper Oxide CuO Powder:
Copper oxide is insoluble in water and ethanol, soluble in acid, ammonium chloride and potassium cyanide solutions. It slowly dissolves in ammonia solution and can react with strong bases. Copper oxide is mainly used for making rayon, ceramics, glaze and enamel, batteries, petroleum desulfurizes, insecticides, hydrogen production, catalysts, green glass, etc.

 How is Cuprous Oxide CuO powder produced? 
There are several methods of industrial production of copper oxide
1. Copper powder oxidation method
Using copper ash and copper slag as raw materials, it is roasted and heated with coal gas for preliminary oxidation to remove moisture and organic impurities in the raw materials. The generated primary oxide is naturally cooled, and after pulverization, it undergoes secondary oxidation to obtain crude copper oxide. The crude copper oxide is added to a reactor pre-installed with 1:1 sulfuric acid, and the liquid is reacted with heating and stirring until the relative density of the liquid is doubled, and the pH value is 2 to 3 as the end of the reaction, and a copper sulfate solution is generated. After clarification, under heating and stirring conditions, iron shavings are added to replace copper and then washed with hot water until there is no sulfate and iron. After centrifugal separation, drying, oxidation roasting at 450°C for 8 hours, cooling, crushing to 100 meshes, and then oxidation in an oxidation furnace to obtain copper oxide powder.
2. Nitration of copper wire or copper powder
Dissolve the copper wire or copper powder in 6mol/L nitric acid to keep the copper in excess, heat the solution to a pH value of 3-4 to remove the iron hydroxide precipitate, then mix it with 10% (mass) sodium carbonate solution and heat to boiling. Alkaline salt is precipitated, discard the supernatant, wash thoroughly with water, filter and dry. The dried basic copper carbonate is heated and decomposed into black copper oxide powder under a small fire with sufficient stirring: CuCO3·Cu(OH)2=2CuO+CO2↑+H2O
When no more carbon dioxide is produced, the decomposition is complete.
3. Copper nitrate thermal decomposition method
The electrolytic copper is dissolved in dilute nitric acid and evaporated to dryness on a water bath, and then heated in a desiccator from 90°C to 120°C very slowly. When the soft basic salt is formed, it is boiled in water, filtered and dried; then it is slowly heated to 400℃ to remove most of the nitric acid; then crushed and heated to 850℃ for 1h to decompose into oxidation copper. To make the reaction more complete, the product can be pulverized again, heated at about 700°C for 1 hour, and then placed in a desiccator to cool.
4. Conductive water dissolution method
Dissolve high-purity copper nitrate with conductive water, filter, add excess high-purity NH3·H2O to the clear liquid, filter out impurities and precipitate, and use high-purity nitric acid to neutralize the filtrate to precipitate copper hydroxide. Filter, wash once with conductive water, add nitric acid to dissolve the precipitate, add high-purity ammonium carbonate to precipitate copper carbonate, then wash, spin dry, dry in an oven at 200°C, burn at 450-550°C for 3 to 4 hours, and get Spectral pure copper oxide:
5. Copper carbonate thermal decomposition method
Put copper powder or copper wire in a fume hood with as little 6mol/L nitric acid as possible to completely dissolve it. If the solution is opaque, it needs to be filtered. Besides, the sodium carbonate solution is mixed with the copper nitrate solution and boiled to generate black basic salt precipitation. When the solid settles, discard the supernatant liquid, fully wash, filter, and dry by decantation. Put it on an evaporating dish and heat it with a small fire with sufficient stirring to decompose it into copper oxide.


Applications of Cuprous Oxide CuO powder:
As a significant product of copper mining, copper(II) oxide is the starting point for the production of other copper salts. For example, many wood preservatives are produced from copper oxide.
Cupric oxide is used as a pigment in ceramics to produce blue, red, and green, and sometimes gray, pink, or black glazes.
It is also incorrectly used as a dietary supplement in animal feed. Due to low bioactivity, negligible copper is absorbed.
It is also used when welding with copper alloys.
A copper oxide electrode formed part of the early battery type known as the Edison–Lalande cell. The copper oxide was also used in a lithium battery type.
Besides, copper(II) oxide can be used as catalysis, superconductivity, ceramics; and catalyst carriers, electrode activity materials;
glass, porcelain colorants, optical glass polishing agent, oil of desulfurized; the propellant rocket fuel speed catalyst.

Indium Oxide In2O3 Powder CAS 1312-43-2

About Indium Oxide In2O3 Powder:
Indium oxide is an amphoteric oxide of indium, and the molecular formula is 2O3. The pure product is a white or light yellow amorphous powder, which is heated to reddish-brown. Indium oxide is a new n-type transparent semiconductor functional material having width disabled bandwidth, smaller resistivity and higher catalytic activity, and has been widely used in optical fields, gas sensors, and catalysts. In addition to the above functions, there is also an indium oxide particle size, surface effect, quantum dimensional effect, small dimensional effect, macroscopic quantum tunnel effect.
Indium oxide is presented in hydrogen or another reducing agent, heated to 400 to 500 ° C, reduced metal indium or low-cost oxide. The low-level oxide is separated at high temperatures. Further, at a high temperature, it can react with metal indium solubilized in acid, but the more difficult it is, and the moisture absorption also disappears. When hydrogen is reduced by heating through hydrogen, metal indium is produced.
Indium oxide is insoluble in water but can be dissolved in acid, while crystalline oxides are not soluble in water. The crystals are divided into two phases, cubic (diamond type) and diamond (corundum). The bandgap between the two phases is 3eV. The parameter of the cubic phase is listed in the information box. A rhombic phase is produced at high temperatures and is produced using a non-balanced growth method. Its spatial group R3C No. 167, Piersson symbol HR30, A = 0.5487 nm, b = 0.5487 nm, C = 0.57818 nm, z = 6, the calculation density is 7.31 g / cm3.
Indium mixed indium film (IN2-XCRXO3) is a magnetic semiconductor, a single-phase crystal structure, and a high carrier concentration semiconductor behavior having high-temperature ferromagnetic properties. As the material of the rotating syringe, it can be in the spinning electronics.
Indium oxide polycrystalline films doped with Zn have high conductivity (conductivity to 105 S / m), even with higher superconductivity at temperatures in helium. The superconducting transition temperature Tc is related to the doping and the film structure, less than 3.3k. Feel free to send an inquiry to get the latest price if you would like to buy Indium Oxide In2O3 Powder in bulk.

Performance of Indium Oxide In2O3 Powder:

In the presence of hydrogen or other reducing agents, heating to 400 ~ 500 ℃ can be reduced to metal indium or low-cost indium oxide.
Decomposes to lower oxides at high temperatures. In addition, it can react with metal indium at high temperature. Although In2O3 generated by low-temperature burning is easily soluble in acid, the more complete the high-temperature treatment is, the more difficult it is to dissolve, and the hygroscopicity also disappears. When indium trioxide is reduced with hydrogen under red heat, metal indium is generated.

How is Indium Oxide In2O3 Powder produced?
1. The high-purity metal indium is burned in the air or indium carbonate is calcined to produce In2O, Ino and In2O3, and the high-purity In2O3 can be obtained by finely controlling the reduction conditions. The indium trioxide ceramic powder with an average particle size of 20nm can also be prepared by the spray combustion process.
2. When indium hydroxide is burned to prepare indium trioxide, if the temperature is too high, In2O3 has the possibility of thermal decomposition; if the temperature is too low, it is difficult to complete dehydration, and the oxide generated has hygroscopic property. Therefore, heating temperature and time are important factors. In addition, because In2O3 is easily reduced, it must always be kept in an oxidizing atmosphere.
3. Indium hydroxide is burned in the air at 850℃ to a constant weight to generate In2O3, and then heated in the air at 1000℃ for 30min. Other indium nitrates, indium carbonate, and indium sulfate can also be burned in the air to make indium trioxide.
