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.
- Magnets of Samarium cobalt alloy are stronger than that of Iron and hence, they are used in microwave application.
- Samarium metal also used in optical lasers and infrared absorbing glasses and as a neutron absorber.
