Product Name	MF	Purity	Particle Size	Molecular weight	Density	Color
niobium boride	NbB2	99%	5-10um	114.528	6.97 g/cm3	gray

99%	18.9%	80.3%	0.01%	0.09%	0.02%	0.06%

How is Niobium Boride NbB2 PowderProduced?
NbB2 can be synthesized by the stoichiometric reaction between constituent elements, in this case, Nb and B. This reaction provides for precise stoichiometric control of the materials. Reduction of Nb2O5 (or NbO2) to niobium diboride can also be achieved via metallothermic reduction. Inexpensive precursor materials are used and reacted according to the reaction below:
Nb2O5 + 2 B2O3 + 11 Mg → 2 NbB2 + 11 MgO
Mg is used as a reactant in order to allow for acid leaching of unwanted oxide products. Stoichiometric excesses of Mg and B2O3 are often required during metallothermic reductions in order to consume all available niobium oxide.
Borothermal reduction of NbO2 with elemental boron via solid‐state reaction was proposed by Jha and coworker to obtain nanorods (40 × 800 nm2)
A variation of the borothermal reduction in molten salt was proposed by Ran and co-workers using Nb2O5 with elemental boron to produce nanocrystals (61 nm).
Nanocrystals of NbB2 were successfully synthesized by Zoli's reaction, a reduction of Nb2O5 with NaBH4 using a molar ratio M: B of 1:4 at 700 °C for 30 min under argon flow.
Nb2O5 + 13/2 NaBH4 → 2 NbB2 + 4Na(g,l) + 5/2 NaBO2 + 13 H2(g)

Applications of Niobium Boride NbB2 Powder:
NbB2 is an ultra-high temperature ceramic (UHTC) with a melting point of 3050° C. Its relatively low density of about 6.97 g/cm3 and good high-temperature strength make it a candidate for high-temperature aerospace applications, such as hypersonic flight or rocket propulsion systems. The ceramic has high thermal conductivity and electrical conductivity (resistivity of 25.7 Ω Ybcm, Cte of 7.7 Yb10 −6°C−1), and has the same properties as titanium diboride, zirconium diboride, hafnium diboride and tantalum diboride with the same structure
NbB2 parts are usually hot pressed or spark plasma sintered (mechanical pressure is applied to the heated powder) and then machined into shape. The covalency of NbB2 and the presence of surface oxides hinder the sintering of NbB2, and the particles are coarsened and then densified in the sintering process.NbB2 can be sintered without pressure by using sintering additives such as boron carbide and carbon. These sintering additives react with surface oxides to increase the sintering force, but the mechanical properties of NbB2 decrease compared with hot pressing sintering.

About Single And Multi-Layer Graphene Powder:
Graphene is a kind of new material that is composed of carbon atoms connected by SP ² tightly packed into a monolayer two-dimensional honeycomb lattice structure. Graphene has excellent optical, electrical and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedical and drug delivery, etc., and is considered a revolutionary material in the future.
Single-layer graphene
What is graphene a single layer of? Graphene is a single layer (monolayer) of carbon atoms, tightly bound in a hexagonal honeycomb lattice. It is an allotrope of carbon in the form of a plane of sp2-bonded atoms with a molecular bond length of 0.142 nanometres. Single-layer Graphene refers to a two-dimensional carbon material consisting of a layer of carbon atoms that are periodically packed together in a benzene ring structure (i.e., a hexagonal honeycomb structure).
Graphene (few-layer)
What is few layer graphene? Graphene (few-layer) refers to a two-dimensional carbon material composed of 3-10 layers of carbon atoms stacked in a benzene ring structure (i.e. hexagonal honeycomb structure) in different stacking ways (including ABC stacking, ABA stacking, etc.).
Multilayer graphene
Multilayer graphene, also known as multi-layer graphene, refers to a two-dimensional carbon material composed of the benzene ring structure (namely hexagonal honeycomb structure) with a thickness of more than 10 layers and less than 10nm and the carbon atoms stacked periodically and closely in different stacking ways (including ABC stacking, ABA stacking, etc.).
Single-layer graphene has emerged as a high-performance material capable of replacing outdated technologies, benefiting countless industries. Graphene is very light, but it's very durable, and it's able to conduct high levels of electricity through very small amounts of material. Applications for graphene include small electrical circuits and sockets, medical devices, and solar cells. Because of its flexibility, many industry leaders have started using graphene to ensure the safety of their various devices without compromising their efficiency. Single-layer graphene has proven to be a very reliable resource that is both economical and energy-efficient.
Single-layer graphene of the ACS material is available in powder or dispersed form. Single-layer graphene powders are produced using a combination of thermal peel reduction and hydrogen reduction. The monolayer graphene dispersions were created using our own mechanical stripping and dispersion methods. Both products do not contain metal ions and can be used as a conductive agent to improve the high rate of charge and discharge capacity of the battery. In addition to batteries, single-layer graphene powders and dispersants are used in supercapacitors, lead-acid batteries, solar cells, semiconductor chips, graphene films, coatings, and many biological materials.Biomedicalmaterialsprogram is a trusted global Single And Multi Layer Graphene Powder supplier. Feel free to send an inquiry about the latest price of Graphene at any time.
Graphene layers consist of ultra-thin layers of carbon atoms arranged in a hexagonal honeycomb lattice. Graphene films produced by chemical vapor deposition (CVD) are polycrystalline in nature, with multiple small graphene domains growing and merging into a continuous film. Compared to single-layer graphene, fewer layers have the potential to develop into materials or heterostructures -- by inserting different substances into their layered structures.

How is Single And Multi-Layer Graphene Powder Produced?
The common powder production methods of graphene are the mechanical stripping method, REDOX method, SiC epitaxial growth method, and chemical vapor deposition (CVD) method.
Dispersible monolayer graphene was prepared by complete reduction of GO prepared by Hummer method. Commonly used preparation methods can produce denser graphene, which tends to aggregate. The resulting graphene clumps are insoluble in water or other polar solvents and can no longer disperse, making further treatment difficult. Our dispersible graphene avoids this problem and can be re-dispersed in many solvents.

Applications of Single And Multi-Layer Graphene Powder:
With the gradual breakthrough of mass production and large size problems, the industrialized application of graphene is accelerating. Based on the existing research results, the first fields to achieve commercial application may be mobile devices, aerospace, new energy batteries. With a unique combination of novel electronic, optical and mechanical properties, graphene-based nanomaterials have found applications in energy generation and storage. For example, they are used in basic research, transmission photovoltaic devices, transistors and batteries, new energy batteries, sensors and flexible electronic devices, aerospace fields, photodetectors and biomedical applications (such as drug delivery, biological imaging and tissue engineering), etc.
The research and application development of graphene continue to heat up. Graphene and graphene-related materials are widely used in battery electrode materials, semiconductor devices, transparent display screens, sensors, capacitors, transistors and other aspects. Due to the excellent performance and potential application value of graphene materials, a series of important advances have been made in many fields such as chemistry, materials, physics, biology, environment, energy and so on. Researchers are trying different methods in different fields to produce high-quality, large-area graphene materials. And through the continuous optimization and improvement of the preparation process of graphene, the preparation cost of graphene can be reduced so that its excellent material properties can be more widely used, and gradually toward industrialization.

Storage Condition of Graphene Powder:
The damp reunion will affect graphene powder dispersion performance and using effects, therefore, graphene powder should be sealed in vacuum packing and stored in cool and dry room, the graphene powder can not be exposure to air. In addition, the graphene powder should be avoided under stress.

Selenium powder Se powder CAS 7782-49-2

About Selenium powder Se powder:
Selenium powder, chemical formula Se, black gray nonmetal, soluble in concentrated sulfuric acid, chloroform, slightly soluble in carbon disulfide, toxic, insoluble in water, ethanol. Selenium powder is usually in the form of powder or granule, with pure appearance, consistent color, purity up to 99.99%, no soil and other impurities, stable composition and even moisture.
Selenium is a chemical element with the symbol Se and an atomic number of 34. It is a nonmetal (much less thought of as a nonmetal), somewhere between sulfur and tellurium on the periodic table, and also similar to arsenic. Selenium is found in metallic sulfide ores, where it partially displaces sulfur. Commercially, selenium is a by-product of the refining process of these ores, usually during the production process. Pure selenium or selenate compounds are known but are rare. Today the main commercial uses for selenium are glassmaking and pigments. Selenium is a semiconductor used in photovoltaic cells. The once important applications of electronic products have been largely replaced by silicon semiconductor devices. Selenium is still used in several types of DC power surge protectors and one type of fluorescent quantum dot. Biomedicalmaterialsprogram is a trusted global Selenium powder Se powder supplier. Feel free to send an inquiry about the latest price of Selenium powder at any time.
Although trace amounts of selenium are necessary for cellular function in many animals (including humans), the elements of selenium and (especially) selenium salts are toxic in even small doses, leading to selenium poisoning. Selenium is an ingredient in many multivitamins and other dietary supplements, as well as infant formula, and is a component of the antioxidant enzymes glutathione peroxidase and thioredoxin reductase (which indirectly reduce certain oxidizing molecules in animals and some plants) and three diiodide enzymes.

Features of selenium Se powder CAS 7782-49-2:
Amorphous red powder, becoming black on standing and crystalline on heating; vitreous and colloidal forms may be prepared. Amorphous form softens at 40 °C and melts at 217 °C. It rarely occurs in its elemental state in nature, or as pure ore compounds. Soluble in concentrated nitric acid and in (liquid form) common alkalies. Forms binary alloys with silver, copper, zinc, lead, etc. Low toxicity. A necessary nutritional factor for animals.

How is Selenium powder Se powder Produced?
Selenium is a kind of sparse element, and there is no independent selenium production plant in the world. Selenium is associated with electrolytic copper and nickel, which exists in anode mud of electrolytic anode. There are many methods to recover and purify selenium and tellurium from copper electrolytic anode mud, such as caustic oxidation pressure leaching, oxidation roasting high-temperature leaching, low-temperature oxidation roasting, dilute sulfuric acid leaching, etc. Selenium and tellurium are reduced mostly by sulfur dioxide reduction and copper reduction. Due to the method of pre-roasting and oxidation, the maintenance cost of complex power equipment is high, the sulfur dioxide gas is harmful to the human body and the environment, and the recovery and purity of selenium and tellurium are high. With H2O2 as oxidant, selenium and tellurium were oxidized in a weakly acidic solution. After solid-liquid separation, selenium and tellurium were separated by adjusting pH, and selenium and tellurium were reduced by Na2SO3 under hydrochloric acid acidification. The recoveries of selenium and tellurium were 99% and 98%, respectively, and the purity of both of them could reach 99%.

Applications of Selenium powder Se powder:
Selenium can be used in different fields, depending on its purity. Selenium is now used in a wide variety of applications, from glass and metallurgy to pigments, agriculture and electronics. Selenium powder is mainly used in the production of selenium dioxide as electrolytic manganese melting catalyst, other applications in rectifier, photographic exposure agent, petroleum working catalyst, copy toner cartridge, selenium photosensitive plate, alloy, feed and pigment in plastics, paint, enamel and glass, medical and health care medicine and other industries.

Storage Condition of selenium Se powder:
The damp reunion will affect Se powder dispersion performance and using effects, therefore, selenium Se powder should be sealed in vacuum packing and stored in cool and dry room, the selenium Se powder can not be exposure to air. In addition, the Se powder should be avoided under stress.

Aluminum Diboride AlB2 Powder CAS 12041-50-8

About Aluminum Diboride AlB2 Powder:
Aluminum boride (AlB2) is a binary compound formed by aluminum element and boron elements. It is a red solid under normal temperature and pressure. It loses its surface gloss when heated. It is stable in cold dilute acid and decomposed in hot hydrochloric acid and nitric acid.

Aluminium boride (AlB2) is one of two compounds of aluminum and boron, the other is AlB2, and they are commonly referred to as aluminum boride. AlB12 is a black and shiny monoclinic crystal with a specific gravity of 2.55 (18°C). It does not dissolve water. The single crystal of AlB2 is parallel to the hexagon of the base.

The structure of aluminum diboride (AlB2) is similar to that of graphite flakes. There are Al atoms between B atoms and B atoms, which is very similar to the structure of magnesium diboride. The AlB2 single crystal exhibits metal conductivity along an axis parallel to the hexagonal plane of the substrate.

Aluminum boride powder is considered a hazardous substance because it reacts with acid and hydrogen to generate toxic gases. For example, it reacts with hydrochloric acid to release borane and aluminum chloride.

The crystal structure of AlB2 is often used to describe the prototype structure of intermetallic compounds. There are many structure types in the AlB2 structure family. Feel free to send an inquiry to get the latest price if you would like to buy Aluminum Diboride AlB2 Powder in bulk.

Properties of AlB2 powder:

Tr-AlB2-P2 gray black powder 5-10um 98.5% 2.12g/cm3 12041-50-8 234-923-7
AlB2 yields a solution having a reducing soluble in dilute hydrochloric acid, and the solution may contain HB (OH), is not soluble in sulfuric acid but can be dissolved in nitric acid. Above 920 degrees AlB2 broken down into AlB12.

Product performance of Aluminum Diboride AlB2 Powder:
Aluminum diboride is an ionic compound, with a hexagonal crystal structure. Aluminum boride at an absolute temperature of slightly 40K (equivalent to -233 ℃) will be transformed into a superconductor. And its actual operating temperature is 20 ~ 30K. To reach this temperature, we can use liquid neon, liquid or closed-cycle refrigerator to finish cooling. Compared to the current industry using liquid helium to cool the niobium alloy (4K), these methods are more simple and economical. Once it is doped with carbon or other impurities, magnesium diboride in a magnetic field, or there is a current passing, the ability to maintain the superconducting is as much as niobium alloys, or even better.

How is Aluminum Diboride AlB2 Powder produced?
Amorphous boron powder and aluminum powder are used as raw materials to prepare aluminum boride powder by powder metallurgy.

X-ray diffractometer and scanning electron microscope were used to determine the phase composition, relative content and micromorphology of the product, and the influence of buried powder on the phase composition of the product was studied, and the optimal process parameters of the synthesis process were determined.

The structure of aluminum boride is similar to that of intermetallic compounds, and its structure mainly depends on the crystal structure of aluminum metal and boron rather than their valence relationship.

Diboron silane AlB2 indicates that the two elemental substances are formed by the reaction above 600°C. It is a layered structure in which Al atoms directly overlap (A, A-mode), and B atoms are filled in the triangular column formed by the direct overlap of Al atoms, that is, the boron layer is between the two aluminum layers.

The boron layer is similar to the graphite structure. The boron atoms are connected into a hexagonal network. The distance between each B atom and the other three B atoms is 0.173nm. There are six Al atoms connected to B, and they are wrapped on the top of the triangular pillar. AlB2 can be dissolved in dilute hydrochloric acid to produce a reducing solution, which may contain HB(OH)+3. AlB2 does not decompose dilute sulfuric acid but can decompose in nitric acid. AlB2 decomposes to AlB12 above 920℃.

Applications of Aluminum Diboride AlB2 Powder:
Aluminum boride is a random (or rhombic) white or light yellow powder. It can be used as:
Non-toxic flame retardant,
plastics,
rubber,
textiles,
coatings,
superconducting magnets,
transmission lines,
sensitive magnetic field detectors.

Storage conditions of Aluminum Diboride AlB2 Powder:
Aluminum boride nanopowder products 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.

With the development of material technology, the application fields of hafnium diboride ceramics and composite materials are becoming more and more extensive. Obtaining low-cost, high-quality hafnium diboride powder is currently an important research and development director at home and abroad. Hafnium diboride is difficult to sinter. In order to improve the sintering performance, it is necessary to obtain an ultrafine powder. Although nano-powder has superior performance, its cost is high, and it is difficult to disperse during raw material processing, and the process is more difficult. Therefore, the development of sub-micron hafnium diboride powder has been paid more and more attention.

Hafnium diboride belongs to the class of Ultra-high-temperature ceramics, a type of ceramic composed of hafnium and boron. It has a melting temperature of about 3250 °C. It is an unusual ceramic, having relatively high thermal and electrical conductivities, properties it shares with isostructural titanium diboride and zirconium diboride. It is a grey, metallic-looking material. Hafnium diboride has a hexagonal crystal structure, a molar mass of 200.11 grams per mole, and a density of ~10.5 g/cm³.

Hafnium diboride is often combined with carbon, boron, silicon, silicon carbide, and/or nickel to improve the consolidation of the hafnium diboride powder (sintering). It is commonly formed into a solid by a process called hot pressing, where the powders are pressed together using both heat and pressure.

Features of Hafnium diboride HfB2 powder:
Hafnium diboride is an ultrahigh temperature ceramic composed of hafnium and boron. It has a melting temperature of about 3250 degrees Celsius. It is an unusual ceramic, having relatively high thermal and electrical conductivities, properties it shares with isostructural titanium diboride and zirconium diboride. It is a grey, metallic looking material. Hafnium diboride has a hexagonal crystal structure, a molar mass of 200.11 grams per mole, and a density of 10.5 grams per cubic centimeter.

How is Hafnium Diboride HfB2 Powder produced?
The combustion synthesis method of high-purity hafnium diboride powder is realized according to the following steps:
1. Mix the basic raw materials and diluents. The basic raw materials include hafnium dioxide, boric anhydride and magnesium powder. The percentages by weight are: hafnium dioxide: 30% to 60%, boric anhydride: 10% to 40%, magnesium powder ：15%～50%, the weight of the added diluent hafnium diboride is 0～3 times of the basic raw material;

2. Drying and mixing;

3. Load the uniformly mixed raw material powder into a graphite boat, and then put it into a closed pressure vessel. The closed pressure vessel is cooled by circulating water, and the reaction is maintained under a protective atmosphere with a pressure of 0-5Mpa or under vacuum conditions. The raw materials are self-propagating combustion and transformed into products;

4. Take out the product after cooling. The product is a mixture of hafnium diboride and magnesium oxide. The magnesium oxide is removed by acid washing, and then the hafnium diboride is washed with water, filtered and dried to obtain hafnium diboride powder.

Applications of Hafnium Diboride HfB2 Powder:
Hafnium diborideis used in wear-resistant coatings. Its use has also been looked at for use in ultra-high-temperature composites in conjunction with silicon carbide (SiC), due to its excellent refractoriness. The addition of silicon carbide improves its oxidations resistance.

The oxidation resistance of hafnium diboride is dependent on the temperature and pressure. At a temperature of 1500 °C and 1 atm of pressure, a protective oxide scale of hafnia forms. When temperatures rise above 1600 °C and pressures drop below 1 atm, the oxidation resistance of HfB2 is dramatically reduced. Under these conditions, the boiling temperature of B2O3 (one of the oxidation products of HfB2) is exceeded and the protective oxide layer.

The material has potential for use in hypervelocity reentry vehicles such as ICBM heat shields or aerodynamic leading-edges, due to its strength and thermal properties. Unlike polymer and composite material, HfB2 can be formed into aerodynamic shapes that will not ablate during reentry.

Hafnium diboride is also investigated as a possible new material for nuclear reactor control rods.

Hafnium diboride is also being investigated as a microchip diffusion barrier. If synthesized correctly, the barrier can be less than 7 nm thick.

Storage Condition of Hafnium diboride HfB2 powder:
Damp reunion will affect HfB2 powder dispersion performance and using effects, therefore, hafnium diboride HfB2 powder should be sealed in vacuum packing and stored in cool and dry room, the hafnium diboride HfB2 powder can not be exposure to air. In addition, the HfB2 powder should be avoided under stress.

About Iron Boride FeB Powder:
Iron boride (FeB) is a gray powder that is insoluble in water. FeB is harder than Fe2B, but more fragile and more likely to break on impact. Feb is a soft ferromagnetic compound that becomes paramagnetic at temperatures above 325°C (617°F).In the air, FeB powders begin to react with ambient oxygen above 300°C. Although a large number of FeB materials are expected to remain stable in air, FeB is a very hard compound (measured by Vickers indentation at 15-22 GPa), it is undesirable on bonded steel because the FeB layer is brittle and tends to flake off steel or iron.
Feb has a zigzag chain of boron atoms coordinated by seven iron atoms. The boron atom has a slightly twisted single-terminated triangular prism iron atom coordination and two boron atom neighbors. The B-B single bond distance is 178 PM, the Fe-B single bond distance is 215 -- 220 PM, and the Fe-Fe single bond distance is 240 -- 272 PM. Each triangular prism shares two rectangular faces with a nearby prism, thus forming an infinite sequence of the prism.
The FeB single crystal is occupied by the bond domain. The bond domain is parallel to the easy magnetization axis and perpendicular to the hard magnetization axis. The structure of a closed domain is described as "rows and twists of asterisks".The bond domain has an obvious direction on the boundary of the main domain, while the closed domain is rhomboid.

How is Iron Boride FeB Powder produced?
The preparation method of iron boride FeB is as follows:
1. It is prepared by mixing boron with iron at a molar ratio of 1∶1 and cheating in argon at 1200 ~ 1300℃.
2. Reaction FeS and BCl3 in hydrogen at temperatures higher than 500℃, or from ferrous chloride solution and sodium borohydride (NaBH4).

Application of Iron Boride FeB Powder:
Fe-based coatings have recently gained attention for their mechanical, friction and corrosion resistance. Compared to the ceramic or cermet types used by humans before them, the iron-based material is relatively cheap, less strategic, and can be produced economically through a variety of thermal methods, and is easy to manufacture and machine.
Iron boride is commonly used to improve wear resistance, corrosion resistance, wear-resistance and oxidation resistance.
Iron boride is used in oil and gas refineries, chemical extraction, automotive, agricultural, stamping, textile extrusion and injection molding industries.
