Uses
Uses & Benefits
  • The most common use of cesium metal is as a drilling fluid. It is also used in optical glass manufacturing.
  • In vacuum tubes and radiation monitor equipment this metal is used as a catalyst promoter.
  
  • 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.
