Uses
Vanadium carbide (VC) and niobium carbide (NbC) are also extremely hard refractory materials. VC can be used as an additive to tungsten carbide (WC) to refine the carbide crystals and to improve the property of the cermet. TiC, ZrC, VC and NbC are commercially used in tool bits for cutting tools.
