3 Uses
3.1 Uses & Benefits
- It has a tendency to get tarnished in the open air, but when alloyed with elements like erbium, vanadium, its hardness levels decreases.
- Its compounds like Erbium oxide is used in safety glasses of welders and metal workers.
- Platinum metal is mainly used in jewellery.
-
Platinum is used as an industrial catalyst in production of nitric acid, silicone and benzene.
