Abstract
This producing method includes: a preparing step of preparing a pair of ceramic sintered bodies at least one of which is formed by a reaction sintering method and contains free silicon; a forming step of interposing a joining slurry between the joined surfaces of the pair of ceramic sintered bodies and thereafter drying the joining slurry, to form a fine particle layer, the joining slurry obtained by dispersing fine particles containing a carbon element in an organic solvent; and a joining step of heating the pair of ceramic sintered bodies in an inert atmosphere with the pair of ceramic sintered bodies held so that the fine particle layer is pressurized, to introduce the free silicon into the fine particle layer, thereby forming a joining layer containing at least silicon carbide so that the pair of ceramic sintered bodies are joined to each other, to obtain the ceramic joined body.
