Uses
Uses & Benefits
  • Lutetium metal is used outside research. It has commercial uses like Industrial catalyst for cracking oil refineries of hydrocarbons .
  
  • Tin and bismuth alloys have a very low melting point and hence it is used in fire detector and the fire extinguishers. It also used in electric solders and fuses.
