Uses

Uses & Benefits
  • The main use of this metal include nuclear fuel which is used to generate electricity yin nuclear power stations.
  • Synthetic elements like transuranium are made from Uranium metal.
  
  • Terbium salts are used in optical devices like laser devices.
  • Terbium’s alloy lengthens and shortens the magnetic field and this effect forms loudspeaker.
