<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a reaction sintered silicon carbide structure which has excellent structural strength, corrosion resistance, durability, and the like in a wide service temperature range from room temperature up to high temperature and can easily and efficiently manufacture even a small-sized structure having an intricate shape with high dimensional accuracy. <P>SOLUTION: The method for manufacturing the reaction sintered silicon carbide structure is characterized as follows. A molded body containing silicon carbide and carbon powders is formed using a core 7, and the molded body has a pore 5 corresponding to the configuration of the core 7 inside. The obtained molded body is subjected to a binder removing treatment to form a degreased body, thereafter the degreased body is heated to be impregnated with molten silicon and to be subjected to reaction sintering, thereby making an integral sintered compact. <P>COPYRIGHT: (C)2009,JPO&INPIT |
