3 Uses
3.1 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.
- Aluminum is used in a various products; for example, cans, foils, kitchen utensils, window frames, beer kegs and aero plane parts, automobile parts, etc.
