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.
- Technetium is a radioactive metal and hence it is used for medical studies and other research purposes.
