Boride Powder

Hafnium Diboride HfB2 Powder CAS 12007-23-7

About Hafnium Diboride HfB2 Powder:
Hafnium boride is a gray crystal with a metallic luster. It has high conductivity and stable chemical properties. 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.

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. Feel free to send an inquiry to get the latest price if you would like to buy Iron Boride FeB Powder in bulk.

How is Iron Boride FeB Powder produced?

Boride Powder

Nickel Boride Ni2B Powder CAS 12619-90-8

CAS No. : 12619-90-8
EINECS No.: 235-723-2
Appearance: powder
Molecular Formula: Ni2B
Molecular Weight: 128.2

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.

Storage Condition of Nickel Boride Ni2B Powder:
The damp reunion will affect Ni2B powder dispersion performance and using effects, therefore, nickel boride Ni2B powder should be sealed in vacuum packing and stored in cool and dry room, the nickel boride Ni2B powder can not be exposure to air. In addition, the Ni2B powder should be avoided under stress.

Packing & Shipping of Nickel Boride Ni2B Powder:
We have many different kinds of packing which depend on the nickel boride Ni2B powder quantity.
