Uses & Benefits
- Uses of Scandium are limited to research purpose only. However, it has very low density and higher melting point.
-
Its compounds like scandium iodide is used in mercury vapor lamps to produce very bright white light.
- 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.
