Hafnium Crystal Bar Properties

  • Hafnium has good corrosion resistance.
  • Hafnium is easily dissolved in hydrofluoric acid to form fluorine complexes.
  • Hafnium can also be directly combined with oxygen, nitrogen, and other gases to form oxides and nitrides at high temperatures.
  • Hafnium is relatively stable in the air.
  • Powdered Hafnium is very easy to burn.
  • Hafnium has a large thermal neutron capture cross-section and outstanding nuclear energy. 
  • Hafnium has fast heat absorption and release.

Hafnium Crystal Bar Applications

  • It is mainly used to produce hafnium-based alloy materials. 
  • It can be used as a structural material for jet engines and missiles.
  • It can be used as a blade for turbojet aircraft and in freezing-point pressure jet engines.
  • It can be used to make valves, nozzles, and other high-temperature parts.
  • It is used as an additive in nickel-based high-temperature alloys.
  • It is used in CVD evaporation coating.
  • It is used in the field of atomic energy or the military.
