Facts

Interesting Facts
  • Thorium metal is used as an alternate option over Uranium for nuclear fuel.
  • Thorium metals appearance (silvery white, soft) is somewhat similar to Lead metal.
  
  • 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
  • Thorium metal is used as an allying agent for Magnesium, It imparts greater strength and resistance to temperature.
  • compound of this metal Thorium oxide is used as an industrial catalyst.
  
  • 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.
