Method of joining a porous silicon carbide body and a silicon carbide-silicon composite

摘要

A method of joining a silicon carbide body and a silicon carbide-silicon composite, including a step of applying an adhesive paste 3 consisting of silicon carbide powder and a binder component to either or both of a porous silicon carbide body 1 and a silicon carbide-silicon composite 2 formed by impregnating a silicon carbide body with silicon such that said porous silicon carbide body and said silicon carbide-silicon composite are caused to adhere to each other, a step of causing a volatile constituent to evaporate from said adhesive paste 3 such that a porous silicon carbide adhesion layer 3 is formed between said porous silicon carbide body and said silicon carbide-silicon composite, and a step of causing the silicon in said silicon carbide-silicon composite to permeate said adhesion layer 3 through a heat treatment after the previous step such that said adhesion layer 3 is densified.
