3 Uses
3.1 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.
- Actinium metal has a great source of alpha rays but it is hardly used outside research purpose.
