Uses
Uses & Benefits
  • Terbium salts are used in optical devices like laser devices.
  • Terbium’s alloy lengthens and shortens the magnetic field and this effect forms loudspeaker.
  
  • 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.
