Uses

Uses & Benefits
  • 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.
  
  • 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.
