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.
  
  • Gallium arsenide is a very important component of many semiconductors and led manufacturing.
  • Gallium nitride is also know as a semiconductor and it is used in Blu-ray technology, mobile smartphones and LED.
