| 摘要 |
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 titanium carbide, nitride or carbonitride, 0.1-5% by weight (based on silicon carbide) of boron or a boron compound in terms of boron, 0.1-5% by weight (based on silicon carbide) of carbon or a carbon compound in terms of residual carbon and the balance being substantially silicon carbide. |
