| Hafnium powder, ultra-fine hafnium powder |
| Molecular formula: Hf |
| CAS Number: 7440-58-6 |
| Properties: gray-black metal powder |
| Melting point: 2227℃ |
| Boiling point: 4602℃ |
| Density: 13.31g/cm3 |
| Uses: commonly used in X-ray cathode and tungsten wire manufacturing industry. Pure hafnium has plasticity, easy processing, high temperature resistance and corrosion resistance, and is an important material in the atomic energy industry. Hafnium has a large thermal neutron capture cross-section and is an ideal neutron absorber. It can be used as a control rod and protection device for nuclear reactors. |
