PURPOSE: To obtain, at a low cost, a silicon carbide material excellent in thermal shock resistance, oxidation resistance and mechanical strength characteristics. CONSTITUTION: This material having a SiC-Si composite composition is obtained by impregnating the pores of a SiC molded form of 0.75-0.86 in the ratio R (d/D) (d is the bulk specific gravity of the molded form; D is the true specific gravity) with Si at a rate >=R<(2/3)> . |
