ABSTRACT:
Sintered ceramic products comprised of from about 55 to about 99.5 percent by weight of silicon carbide co-sintered with from about 0.5 to about 45 percent by weight aluminum nitride containing a dispersion of free carbon in amounts between about 0.5 and about 4.0 percent by weight of the product are described. The sintered products have a bulk density of at least 75 percent of the theoretical density of silicon carbide. The products are produced by sintering, under substantially pressureless conditions, mixtures of silicon carbide, carbon, or a carbon source material, and aluminum nitride. The aluminum nitride component, in ranges of from about 3.0 to about 45 percent, may be initially mixed with the silicon carbide and carbon or carbon source material. In ranges of from about 0.5 to about 3.0 percent, the aluminum nitride component may be added to the mixture in vapor form during sintering.
