A process comprises the steps of molding a mixture of usual TiC powder material having a combined carbon content lower than the theoretical value and a required amount of binder metal, sintering the molded mixture at a high temperature of about 1550 DEG to 2500 DEG C, and maintaining the sintered product at the high temperature, whereby the combined carbon content is increased to the highest possible value approximate to the theoretical value and the binder metal is fully effectively fused to the surface of the TiC particles. The resulting product is readily crushable to a powder having greatly improved amenability to sintering.
