Uses & Benefits
- As this metal does not absorb neutrons; It is used in nuclear power stations.
- Its oxide is used in ultra strong ceramics. It is also used in manufacturing Crucibles.
- Terbium salts are used in optical devices like laser devices.
-
Terbium’s alloy lengthens and shortens the magnetic field and this effect forms loudspeaker.
