Uses

Uses & Benefits
  • Dysprosium metal is highly reactive due to which it pure form is not as usual as its alloy.
  • Thi metals alloy is used in magnate as it is resistance to high temperature.
  
  • 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.
