Abstract
A method for producing a sintered silicon carbide body which has excellent strength and the like and in which cracking and breaking are prevented is provided. In the method for producing a sintered silicon carbide body, metallic silicon is, in a vacuum atmosphere or in a non-oxidizing atmosphere, impregnated into a molded body containing silicon carbide and carbon so as to form an impregnated body, and the impregnated body is cooled in a state of being provided with a temperature distribution of 0.1-1.5° C./cm.
Claims9
