Interesting Facts
- Platinum is the rarest metal from the Precious metal categories..
- Commercially Platinum is produced as a byproduct in ores of nickel.
- Naturally occurring minor elements include Cadmium.
- Cadmium is released into atmosphere to control volcanic eruption and forest fires.
- It is used for electroplating of Steel for corrosion resistance.
- It can absorb neutrons and used in nuclear reactor to control atomic fission.

Uses & Benefits
- Platinum metal is mainly used in jewellery.
-
Platinum is used as an industrial catalyst in production of nitric acid, silicone and benzene.
- It has very limited uses as it is a toxic metal and it can cause birth defects, cancer, etc.
-
Almost 80% of Cadmium metal is used in Nickel cadmium Batteries and now it is getting replaced with nickel hydride.
