How is Titanium Diboride TiB2 Powder produced?
Titanium Diboride TiB2 is the most stable of several titanium boron compounds. This material does not appear in nature, but it can be synthesized by carbothermal reduction of TiO2 and B2O3. Like most other covalently bonded materials, TiB2 is resistant to sintering and is usually compacted by hot pressing or hot isostatic pressing. Pressureless sintering of TiB2 can achieve high density but requires liquid sintering aids such as iron, chromium and carbon.

TiB2 does not naturally exist on the earth. Titanium diboride powder can be prepared by various high-temperature methods, such as direct reaction to prepare titanium or its oxide/hydride. When elemental boron exceeds 1000°C, carbothermal reduction by thermite reaction has been developed in various synthesis pathways. Electrochemical synthesis and solid-state reaction were used to prepare more refined titanium diboride in large quantities.

Application of Titanium Diboride TiB2 Powder:

Titanium Diboride (TiB2) is a hard material with high strength and high wear resistance at elevated temperatures. The high density, combined with the high elastic modulus and high compressive strength, has to lead to its use in armor components.
It is unaffected by most chemical reagents and has excellent stability and wettability in liquid metals such as zinc and aluminum. This, along with its high electric conductivity, has led to its use in Hall- Héroult cells for aluminum production. It is also used as crucibles for molten metals.Due to its high hardness, extremely high melting point and chemical inertness, TiB2 is a candidate material for many applications.

Ballistic armor
The combination of high hardness and medium strength makes it attractive for ballistic armor, but its relatively high density and difficulty in forming shaped parts make it less attractive than some other ceramics.

Aluminum Smelting
The chemical inertness and good conductivity of TiB2 have made it used as a cathode in Hall-Heroult batteries used for primary aluminum smelting. It can also be used as a crucible and metal evaporation boat for processing molten metal.

Other uses
High hardness, medium strength and good wear resistance make titanium diboride a candidate material for sealing parts, wearing parts and composite materials with other materials and cutting tools.
Used in combination with other major oxide ceramics, TiB2 is used to form composite materials, where the presence of the material helps increase the strength and fracture toughness of the matrix.
Potential applications of TiB2
The current uses of TiB2 are almost limited to special applications in the fields of impact-resistant armor, cutting tools, crucibles, neutron absorbers and wear-resistant coatings.

TiB2 is widely used as a vaporizer for vaporizing aluminum. For the aluminum industry, it is a selective material that can be used as an inoculant for grain refinement when casting aluminum alloys because of its implantability, low solubility in molten aluminum and good electrical conductivity.

TiB2 films can be used to provide wear and corrosion resistance to inexpensive and/or strong substrates.

Chemical Composition of Niobium Boride NbB2 Powder:

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.

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.

It hardly reacts with all chemical reagents (except hydrofluoric acid) at room temperature. It is prepared by mixing hafnium dioxide, boron oxide or boron carbide, carbon powder and heating, or by reducing hafnium tetrachloride and boron trichloride through hydrogen reduction at 2,000°C or directly reacting hafnium and boron. It is used as a high-temperature alloy.
 
HfB2 powder has high melting point, high hardness, good electrical and thermal conductivity, and good neutron absorption performance. It has important applications in the fields of ultra-high temperature materials, superhard materials, electrode materials and neutron absorption materials.
 
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.

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.

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.

About Calcium Nitride Ca3N2 powder
In most cases, calcium nitride is usually available in large volumes. Orachemicals provides a wide range of products for hydrogen storage research, advanced fuel cells, and battery applications. Hydrogen is easily produced from renewable energy sources and is the most abundant element in the universe. Hydrogen comes from many sources, such as solid fuels, water, and renewable materials. Hydrogen is non-polluting and will form harmless water during use. Challenges related to the use of hydrogen as an energy source include the development of safe, compact, reliable, and cost-effective hydrogen storage and transmission technology. Currently, hydrogen can be stored in three forms: compressed hydrogen, liquid hydrogen, and chemical storage. High purity, submicron and Nanopowder forms can be considered. Calcium nitride is the main raw material for high-end phosphors. This phosphor is more stable, has better performance, and has better effects at high temperature and high humidity. Last but not least, calcium nitride can also be used as a chemical treatment agent, which is the key to determining the performance of water-based mud. Feel free to send an inquiry to get the latest price if you would like to buy Calcium nitride in bulk.
How is Calcium Nitride Produced?
When calcium burns in the air, it forms Ca3N2 with the oxide CaO. The distilled fibrous metallic calcium is heated to 450°C in a purified nitrogen stream, and then the metallic calcium is nitrided into calcium nitride after 3-4 hours.
Depending on the preparation temperature, the obtained calcium nitride is black at 350°C, milky white at 350 to 1150°C, or golden yellow at 1150°C or higher. It is easy to identify the calcium nitride formed because it can react with moisture or water and produce calcium hydroxide and ammonia.
Applications of Calcium Nitride
Ca3N2 can be used for obtaining reactive nitride ions, Calcium hydride (a desiccant) can be produced by heating calcium nitride with hydrogen at temperatures above 350 °C.

About Nickel Boride Ni2B Powder:
Nickel Boride is a chemical compound of nickel and boron with the formula Ni2B. It is one of the borides of nickel. The formula "Ni2B" and the name "nickel boride" are often used for a nickel-boron catalyst obtained by reacting nickel salts with sodium borohydride. 
Nickel boride catalyst can reduce unsaturated ethers, alcohols, aldehydes, esters, amines and amides to their corresponding saturated compounds without hydrogenation reaction. Unsaturated nitriles can be reduced to primary amines, while epoxides remain unchanged. In addition to sodium borohydride, dimethoxyborane (Meo)2BH4 or lithium borohydride LiBH4 can react with nickel chloride to obtain nickel boride catalysts for such reactions. It is worth emphasizing that only NiCl2 showed catalytic activity in the combined catalytic reduction of 2-methyl quinoline by a variety of transition metal salts, such as CoCl2, NiCl2, CuCl2, CrCl3 and sodium borohydride. Feel free to send an inquiry to get the latest price if you would like to buy Nickel Boride Ni2B Powder in bulk.

How is Nickel Boride Ni2B Powder produced?
Nickel Boride Ni2B can be obtained (together with other nickel borides) by heating sodium borohydride with powdered nickel-metal up to 670 °C in a closed vessel so that the released hydrogen creates a pressure of up to 3.4 MPa. The main reactions can be summarized as
2NaBH4 ↔ 2NaH + B2H6
2Ni + 2B2H6 + NaH ↔ Ni2B + 3BH3 + 2H2 + Na
but other reactions occur, yielding other borides.

Application of Nickel Boride Ni2B Powder:
Nickel boride catalyst is prepared by the reaction of nickel chloride NiCl2 with boron hydrogen reagents such as sodium borohydride NaBH4. It can be used for selective hydrogenation reaction, desulfurization reaction, dehalogenation reaction, hydrolysis reaction, and reduction of nitro and other functional groups.
The nickel boride catalyst prepared by the reaction of NiCl2 and NaBH4 can also be used for desulfurization reaction. Compared with the Raney nickel catalyst used in the traditional desulfurization reaction, it can obtain a higher yield, and at the same time, it can avoid the disadvantages of Raney nickel such as strong alkalinity, flammability and sensitivity to air and moisture.
In addition, thioamides, sulfides and sulfides can all be desulfurized under the catalysis of nickel boride to obtain corresponding hydrocarbons
Primary, secondary, and tertiary aliphatic nitro compounds can be reduced to amines in the presence of nickel boride.
The NiCl2/NaBH4 combination also achieves dehalogenation and hydrolysis reactions, reducing many α-bromoketones to ketones, or dibromo ketones to olefines, and reducing benzyl, allyl, and propargyl esters to the corresponding alkanes.
