Uses & Benefits
- 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.
- Currently known uses of Neptunium metal are limited to research purpose only.
-
Neptunium’s isotope neptunium-237 is used as a neutron detectors.
