Method for producing silicon carbide sintered body
A method for producing a silicon carbide sintered body, comprising adding water to a raw material mixture containing silicon carbide powder, at least one binder, and optionally at least one carbon source other than the silicon carbide and the at least one binder, and subjecting the raw material mixture to kneading, molding, and drying in this order, to obtain a dried body; heating the dried body to remove organic substances from the dried body to obtain a degreased body; and firing the degreased body in an inert atmosphere to obtain a silicon carbide sintered body. The method comprises controlling an expansion/shrinkage rate of the sintered body by adjusting at least one of (1) an amount of the at least one carbon source in the raw material mixture, (2) an amount of the at least one binder in the raw material mixture, and (3) a degreasing rate.
