Abstract
A SiC ceramic material includes a bundle of SiC continuous fibers in a porous SiC ceramic matrix, has thermal insulation properties, a high level of strength and a high degree of toughness. A SiC ceramic structure is made of the SiC ceramic material. It is produced by preparing a pressure-sintered compact using a slurry prepared by mixing SiC powder and carbon powder in a liquid and by gasifying and releasing the carbon powder. The SiC ceramic structure can be produced by heating a reaction preparation containing a bundle of SiC continuous fibers and Si powder to a temperature equal to or higher than the melting point of silicon causing a reaction of the carbon component and Si powder and thereby obtaining a reaction-sintered compact, and by gasifying and releasing the carbon component from the reaction-sintered compact. The SiC ceramic can be produced by a chemical vapor deposition method.
