Uses
Uses & Benefits
  • 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.
  
  • The main use of this metal include nuclear fuel which is used to generate electricity yin nuclear power stations.
  • Synthetic elements like transuranium are made from Uranium metal.
