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.
- Tantalum metal is mainly used in the manufacturing of electron components. Its Oxide layer acts as an insulator.
- Tantalum metal is also used in surgical transplant like replacement of bone, skull plates and as a woven gauze.
