More info

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 (HfB2) Powder Applications

  • Used as a component in high-temperature coatings for aerospace components, such as turbine blades, rocket nozzles, and hypersonic vehicles.
  • Used as a shielding material for reactors and nuclear waste storage containers due to its excellent neutron absorption properties.
  • Used as a thermal barrier coating due to its ability to withstand extreme temperatures and reduce heat transfer.
  • Used as a refractory material in high-temperature furnaces, crucibles, and other industrial applications where high-temperature resistance is required.

Hafnium Boride (HfB2) Powder Storage and Packing

Hafnium Boride (HfB2) Powder should be stored in a sealed container in a dry and cool place, and should not be exposed to air for an extended period. We offer vacuum-sealed packaging including 100g/bag, 500g/bag, 1kg/bag, and 25kg/drum, or we can offer customized packaging as per specific requirements.
