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.
  
  • Dysprosium acts stable in air at room temperature.
  • Dysprosium behaves very much like paramagnetic metal.

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.
  
  • Dysprosium metal is highly reactive due to which it pure form is not as usual as its alloy.
  • Thi metals alloy is used in magnate as it is resistance to high temperature.
