Uses
Uses & Benefits
  • Currently known uses of Hassium metal are limited to research purpose only.
  
  • 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.
