Tantalum carbide (TaC) ke ntho e thata haholo (Mohs hardess 9-10) refractory ceramic material. Ho thatafala ho fetisoa feela ke daemane. Ke phofo e boima, e sootho e atisang ho sebetsoa ka sintering, le thepa ea bohlokoa ea cermet. Ka linako tse ling e sebelisoa e le motsoako o motle oa kristale ho li-alloys tsa tungsten carbide. Tantalum carbide e na le phapang ea ho ba motsoako oa stoichiometric binary o nang le sebaka se phahameng ka ho fetisisa se tsebahalang sa ho qhibiliha, ho 4150 K (3880 ° C). Motsoako oa substoichiometric TaC0.89 o na le sebaka se phahameng sa ho qhibiliha, haufi le 4270 K (4000°C)
