ABSTRACT:
A high quality shaped article of silicon carbide is efficiently produced by using a carbon substrate suitable for the production of a silicon carbide film without generating cracking or breakage. In a method of producing a shaped article of silicon carbide while using a carbonaceous material as a deposition substrate by decomposing halogenated organic silicone compound by a reduction pyrolysis at a high temperature, forming a silicon carbide film layer on a surface of the substrate by CVD and removing the carbon substrate, the carbon substrate is formed of a composite of graphite and amorphous carbon obtained by shaping and firing a mixture of a powdery graphite and an organic substance.
