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.
- Lutetium metal is used outside research. It has commercial uses like Industrial catalyst for cracking oil refineries of hydrocarbons .
