Interesting Facts
- Samarium metals helps stimulating body metabolism.
- Samarium metals was 1st observed by Jean Charles Galissard de Marignac in Dydimia in 1853.
- Zinc metal found (obtain) in many forms like granules, foil, dust and in a powder form.
- The leading producers of Zinc metal are Australia, Canada, China, U.S.A and Peru.

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.
- It is mainly used for Galvanizing other metals.
- It is also used for manufacturing die-casting and it is very essential for automobile industry.
