4 Uses
4.1 Uses & Benefits
- Its ally with steel is used very tough and hence it is used in armor plates, axles, piston rods, tools and crankshafts.
-
Its oxide is used as pigments for glass and ceramics.
- 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.
