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.
- Tin-niobium alloy is used for producing superconducting magnets.
-
Tin salt known as a tin II chloride, it is used as a mordant and as a reducing agent for dyeing calico and silk.
