The SiC ceramic material according to the present invention includes a bundle of SiC continuous fibers in a porous SiC ceramic base material, has heat insulation properties, and has high strength as well as high toughness. The SiC ceramic structure according to the present invention is composed of the SiC ceramic material, and is heated and sintered using a slurry in which SiC powder and carbon powder are mixed in a liquid such as water and a bundle of SiC continuous fibers. Can be produced by vaporizing and releasing the carbon powder. The SiC ceramic structure according to the present invention is obtained by heating a reaction preparation containing a bundle of SiC continuous fibers, a carbon component and Si powder to a temperature equal to or higher than the melting point of silicon, and reacting the carbon component and Si powder. It can also be produced by vaporizing and releasing the residual carbon component from the reaction sintered body. Furthermore, the SiC ceramic structure according to the present invention can also be manufactured by a chemical vapor deposition method. |
