Uses & Benefits
- Platinum metal is mainly used in jewellery.
-
Platinum is used as an industrial catalyst in production of nitric acid, silicone and benzene.
- Polonium metal has different Allotropes, it is used in antistatic devices and for research purpose.
- A 1 gram of Polonium can reach a temperature of 500°C, hence it is used as a heat source for space equipment.
