Facts
Interesting Facts
  • Platinum is the rarest metal from the Precious metal categories..
  • Commercially Platinum is produced as a byproduct in ores of nickel.
  
  • Vanadium is a highly reactive metal, hence it is not found free in nature.
  • Vanadium can be found in almost 65 different types of minerals.

Uses
Uses & Benefits
  • Platinum metal is mainly used in jewellery.
  • Platinum is used as an industrial catalyst in production of nitric acid, silicone and benzene.
  
  • Its ally with steel is used very tough and hence it is used in armor plates, axles, piston rods, tools and crankshafts.
  • Its oxide is used as pigments for glass and ceramics.
