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.
  
  • As this metal does not absorb neutrons; It is used in nuclear power stations.
  • Its oxide is used in ultra strong ceramics. It is also used in manufacturing Crucibles.
