Uses

Uses & Benefits
  • 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.
  
  • It has corrosion resistance and hence it is used to plate other metals.
  • Its alloys are very useful; Nichrome alloy is used in the hot coil of toasters and electric oven.
