Uses
Uses & Benefits
  • It is a liquid metal at room temperature, but it is a toxic heavy metal and hence many uses of mercury are under review or phased out.
  • It is manly used as a catalysts in chemical industry.
  
  • Tantalum metal is mainly used in the manufacturing of electron components. Its Oxide layer acts as an insulator.
  • Tantalum metal is also used in surgical transplant like replacement of bone, skull plates and as a woven gauze.
