Uses & Benefits
- Silver is mainly used for Jewelry and show piece.
- It is used for manufacturing high quality mirrors due to its reflectivity property.
- 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.
