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.
- Holmium metal has an ability to absorb neutrons, so this metal is used in nuclear reactors to keep the chain reactions of elements under control.
-
Alloys of Holmium are used to produce Magnet.
