Uses
Uses & Benefits
- Tin and bismuth alloys have a very low melting point and hence it is used in fire detector and the fire extinguishers. It also used in electric solders and fuses.
- Lutetium metal is used outside research. It has commercial uses like Industrial catalyst for cracking oil refineries of hydrocarbons .
