Tantalum carbide,Chemical formula TaC,Molecular weight 192.96,Carbon content 6.224%,Density 14.3g/cm3 ,Melting point 3875ºC,Boiling point 5500ºC.Tantalum carbide is brown powder with high chemical stability and favorable high—temperature character．It is hard and heavy．Fine TaC powder is an important cermet material．The cutting tool made of it，having a hardness similar to the diamond，can offer resist high temperature lower than 3800ºC ．As an additive of fine crystalline grain to WC hard alloy，TaC powder can improve notably the performance of alloy ．
1: Fine TaC powder is an important cermet material．The cutting tool made of it，having a hardness similar to the diamond，can offer resist high temperature lower than 3800oC;
2: Used as additive in the field of fine ceramic, cutting tool, the mold and the wear-resisting anti-corrosion structural workpice , enhances the alloy’s toughness. Taking TaC powder as NbC powder、Cr2C3 powder, VC powder to inbihit grain growth and improve grain structure, no matter the final product is mine tool in coarse grain or rod alloy in ultra-fine grain, should choose above metal carbide powders in FSSS size . The metal carbide powder additive content is small, the functon of which just adjust WC grain size and improve its structure.
The finer carbide powder additive size is, the better quality of final product will be. Especially for rod alloy in ultra-fine grain , if the size of additive is coarse, will get opposite result.
