Application  :  Niobium Carbide (NbC) and Tantalum Niobium Carbide (TaNbC or TaC+NbC) are used as additives mainly for P-type cutting tools and cermets because of the beneficial effect on hot hardness and toughness. Therefore these products are homogeneous mixed crystals with high purity and narrow particle size distribution.

Niobium Carbide(NbC), Tantalum Carbide (TaC) and Tantalum Niobium Carbide (TaNbC) are usually used as an additive to *WC-Co ready-to-press (Tungsten-Carbide-Cobalt RTP) grade powders in order to enhance the physical properties of the sintered structure of hardmetals and alloys. NbC, TaC and TaNbC are frequently used in steel cutting grade powder attribute to maintain structure edge strength at high temperatures.  In addition, NbC and TaC can be used as a grain growth inhibitor preventing the formation of large grains and increasing the hardness of the sintered part.
Note: * Tungsten carbide powder(WC) is produced by carburization in a hydrogen atmosphere with a mixture of tungsten metal powder and pure black carbon, which is used to manufacture Cemented Tungsten Carbide - Cutting Tools, Wear Parts, Roll & Die, Diamond Tools, Mining Tools etc.
Typical size: 0.7 micron, 0.8 micron, 1.0-1.3 micron, 1.2 micron max. , 1.5 micron max.
