Notes:
The transition-metal carbide cemented by metal has excellent combined properties. In thisstudy, cermets were prepared by vacuum sintering from carbide-metal composite powders. Thetransition- metal oxides (Cr2O3, MoO3, V2O5, Nb2O5 and TiO2), cementing-metal oxides (Co3O4 andNiO), and carbon black were used as raw materials to pre-synthesize composite powders such asCr3C2-Co, Mo2C-Co, VC-Co, NbC-Co and TiC-Ni, by a direct reduction and carburization process invacuum. Results show that the participation of Co3O4 and NiO as well as the vacuum circumstance weregreatly propitious to the carburization of transition-metal oxides into carbides. The carbothermalcondition was greatly improved by the direct reduction and carburization process
