Hafnium Boride Powder is a gray crystal with a metallic luster. It has a large conductivity and excellent thermochemical stability. Hafnium Diboride (HfB2) powder is often used as an anti-ablation material in a high-temperature oxidation environment.
Hafnium Boride Powder's crystal structure belongs to the hexagonal crystal system. As an excellent ultra-high-temperature ceramic material, hafnium diboride (HfB2) has a very high melting point (3380 ℃) and can maintain high strength at high temperatures. It has the characteristics of high hardness, high modulus, high thermal conductivity, low saturated vapor pressure, moderate thermal expansion rate, good thermal shock resistance, high electrical conductivity, etc. It hardly reacts with all chemical reagents (except HF) at indoor temperatures and is widely used in wear-resistant coatings, refractory materials, cutting tools, and aerospace thermal protection systems.
Hafnium Boride Powder HfB2 uses
1.Aerospace: Used in rocket nozzles and hypersonic vehicles for high temperature resistance.
2.High-temperature components: crucibles, electrodes and heating elements due to their ultra-high melting point.
3.Cutting tools: For drills and blades due to its hardness and wear resistance.
4.Semiconductors: Used in gate contacts and interconnects for their conductivity.
5.Refractories: Used in furnace linings and high temperature components.
6.Electrodes: Reliable performance in electrical systems.
7.Sputtering targets: Used in PVD processes to create thin films and coatings.
8.Friction coatings: Reduce friction and wear in industrial and automotive environments.
