Hafnium Diboride HfB2 Puffer:
Hafnium borid or Hafnium disboride can be described as a gray crystal having a metallic luster. It exhibits high conductivity as well as stable chemical characteristics. It does not react with hydrofluoric or other chemicals at roomtemperature. Mixing hafnium bioxide, boron orange or boron caustic, heating it, or using hydrogen reduction at 2500°C to reduce hafnium trioxide and borontrichloride. It is used for high temperature alloys.
Hafnium disboride has a high melting temperature, high hardness. Also, it is very electrically and thermally conductive. It can be used to make superhard materials, electrode materials, neutron absorption and ultra high temperature materials.
With advancements in technology, the applications of hafnium boride ceramicsand of composite materials are growing. At home, and internationally, it is important to be able to get low-cost hafnium triboride powder. Hafnium boride is not easy to sinter. An ultrafine powder can be used to improve the sintering process. Although nano-powder can provide superior performance, it’s expensive and difficult to distribute during raw material processing. It is therefore important to develop sub-micron hafnium disboride powder.
Hafnium diboride belongs to the class of Ultra-high-temperature ceramics, a type of ceramic composed of hafnium and boron. Its melting point for hafnium biboride is 3250 °C. It is metallic in appearance, and grey. Hafnium disboride has hexagonal crystal structures, a molar density of approximately 10.5 grams/cm3, and a weight of 200.11g/mole.
Hafnium disborideis frequently combined with carbon boron, silicon and silicon carbide. This improves the stability of the hafnium powder during sintering. A hot pressing process is used to convert the powders into solids. This involves using heat and pressure.

Hafnium-diboride HfB2 dry powder:
Hafnium triboride, an ultrahigh-temperature clay made from hafnium or boron is known as Hafnium. It is a ceramic with a melting temperature around 3250 Celsius. This is a rare ceramic. It has high thermal conductivities and low electrical conductivities. This is a gray-colored, metallic material. Hafnium disboride’s hexagonal crystal structure has a weight of 200.11g/mole and a density at 10.5g/cm2.
HowHafnium DIboride HafB2 Powderis produced?
Following are steps that will allow you to achieve the high-purity combustion synthesis process of hafnium Diboride Powder.
1. Mix the basic ingredients with the diluents. You will need to mix hafnium oxide, boricanhydride, and magnesia powder as the base raw materials. Based on weight, these percentages include hafnium bioxide: 30% to 60%, and boric anhydride – 10% to 40%. Magnesium powder :15% to 50%. However, the additional diluent hafnium triboride weighs only 0 to 3.
2. Drying and Mixing
3. In a graphite bowl, place the uniformly mixed powder in order to form a paste. Then put it into an enclosed pressure vessel. It is then cooled with circulating waters. Products are created from the raw materials through self-propagating combustion.
4. Let the product cool down before taking it out. After cooling, the product will contain a combination of hafnium boride and magnesia oxide. For hafnium oxide powder, acid washing is used to remove magnesium oxide.
ApplicationsHfB2 PowderHTML3_ :
Hafnium diboride is 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.
This determines the hafnium’s ability to resist oxidation.
HfB2’s strength and thermal property make it a good material for hypervelocity reentry vehicles.
Hafnium boride is also being considered as a new material in order to make nuclear reactor control rods.
Hafnium boride is also being explored as a microchip-diffusion barrier.
