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.
