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.
  
  • It is used for producing chip resistors and contact.
  • Ruthenium oxide is used to coat the anodes cells for chlorine production in chemical industry. It also works as catalysts for ammonia and acetic acid reaction.
