Uses & Benefits
- Magnets of Samarium cobalt alloy are stronger than that of Iron and hence, they are used in microwave application.
- Samarium metal also used in optical lasers and infrared absorbing glasses and as a neutron absorber.
- Platinum metal is mainly used in jewellery.
-
Platinum is used as an industrial catalyst in production of nitric acid, silicone and benzene.
