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.
  
  • Ytterbium metal is used in memory devices and tuneable laser.
  • It is also used as industrial catalyst as the other catalysts are too toxic and polluting.
