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.
  
  • Platinum metal is mainly used in jewellery.
  • Platinum is used as an industrial catalyst in production of nitric acid, silicone and benzene.
