Interesting Facts
- Samarium metals helps stimulating body metabolism.
- Samarium metals was 1st observed by Jean Charles Galissard de Marignac in Dydimia in 1853.
- It is the most reflective element.
- Silver is the second most ductile metal after Gold.
- It is also used in Dentistry as a dental alloys for clips and crowning.

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