5 Uses
5.1 Uses & Benefits
- Dysprosium metal is highly reactive due to which it pure form is not as usual as its alloy.
-
Thi metals alloy is used in magnate as it is resistance to high temperature.
- 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.
