| 1. Appearance and description: |
| High-purity osmium, also known as crystalline osmium, is a silver-gray metal crystal with metallic luster; |
| Molecular weight: 178.49 |
| Melting point: about 2227 ℃ |
| 2. Nature: |
| It has good anti-corrosion performance, is not easy to be attacked by ordinary acid and alkali aqueous solution, and is easily soluble in hydrofluoric acid to form a fluorine complex. At high temperatures, plutonium can also directly combine with oxygen, nitrogen and other gases to form oxides and nitrides; plutonium is relatively stable in the air, and powdered plutonium is very easy to burn; plutonium has a large thermal neutron capture cross section, and plutonium has prominent Nuclear energy is a rare material indispensable for the development of the atomic energy industry. |
| 3. Uses: |
| It is mainly used for the production of hafnium-based alloy materials. Because hafnium has fast heat absorption and exothermic properties (1 times faster than zirconium and titanium), it can be used as a structural material for jet engines and missiles. Rhenium's refractory nature makes it useful as a blade for turbojets and in freezing point pressure jet engines. It can also be used to make valves, nozzles and other high temperature parts. |
