Application  : Tantalum Carbide (TaC) and Niobium Tantalum Carbide (NbTaC) 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.  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. TaC and TaNbC are frequently used in steel cutting grade powder attritions to maintain structure edge strength at high temperatures.  In addition, TaC can be used as a grain growth inhibitor preventing the formation of large grains and increasing the hardness of the sintered part.    
(* Tungsten Carbide powder (WC or WCP) 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.)    

We co-carburizes Tantalum Pentoxide (Ta2O5) and  Niobium Pentoxide (Nb2O5) to manufacture Tantalum Niobium Carbide (TaNbC)  powders  with a wide range of metal ratios.  Tantalum Niobium Carbide (TaNbC)  powders can be tailored to customer's requirements.

Packing: Packed in iron drums of 25kg~50kg net each with inner sealed double covers plastic bottle of 3~5kg net each.
