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.
- It is used for producing chip resistors and contact.
- Ruthenium oxide is used to coat the anodes cells for chlorine production in chemical industry. It also works as catalysts for ammonia and acetic acid reaction.
