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.
- As this metal does not absorb neutrons; It is used in nuclear power stations.
- Its oxide is used in ultra strong ceramics. It is also used in manufacturing Crucibles.
