Facts
Interesting Facts
  • Samarium metals helps stimulating body metabolism.
  • Samarium metals was 1st observed by Jean Charles Galissard de Marignac in Dydimia in 1853.
  
  • Palladium alloys are used for Jewelry contains (95% Palladium and 5% Ruthenium)
  • In the late 1800s, Palladium metal used have more economical value than the Platinum metal.
  • Palladium element is known as a good catalyst

Uses
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.
  
  • Mostly palladium metal is used in catalytic converters. In electronic industry it is used in ceramic capacitors of mobile and computer.
  • It is used in jewellery and dental fillings and crowns.
