3 Uses
3.1 Uses & Benefits
- Dysprosium metal is highly reactive due to which it pure form is not as usual as its alloy.
-
Thi metals alloy is used in magnate as it is resistance to high temperature.
- Terbium salts are used in optical devices like laser devices.
-
Terbium’s alloy lengthens and shortens the magnetic field and this effect forms loudspeaker.
