Abstract
A ceramic compact having a more excellent high temperature strength, toughness and reliability, which comprises a silicon nitride matrix and ceramic fibers uniformly dispersed in the matrix and orientated in a desired direction, said matrix and fibers being closely bonded by sintering, is provided. This compact is produced, for example, by preparing a shaped body of silicon in which ceramic fibers are uniformly dispersed and then bearing and nitriding the shaped body in a nitrogen atmosphere to form a fiber-reinforced silicon nitride sintered compact.
