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 structural materials 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 the nickel-based high-temperature alloy.
It is used in CVD evaporation coating.
It is used in the field of atomic energy or the military.
