ABSTRACT:
A sintered non-oxide ceramic composite high in density, high-temperature strength and toughness and having optionally and widely changeable electrical conductivity is obtained by compacting and sintering a mixed powder comprising 5-95% by weight of at least one compound selected from titanium carbide, nitride and carbonitride, 0.1-5% by weight (based on silicon carbide) of boron or boron compound in terms of boron, 0.1-5% by weight (based on silicon carbide) of carbon or carbon compound in terms of residual carbon and the balance of substantially silicon carbide.
