2 Facts
2.1 Interesting Facts
  • 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
  • Neodymium is not found free in nature, hence it is not a native metal.
  • Neodymium metal found in minerals like Monazite and Bastnaesite.
