METHOD FOR PRODUCING CERAMIC SINTERED COMPACT

摘要

PROBLEM TO BE SOLVED: To obtain a ceramic sintered compact having no gap in a joined part in a method for integrating the joined bodies of unsintered ceramic molded materials by sintering. SOLUTION: There is provided a method for producing a ceramic sintered compact by sintering two or more ceramic molded materials together to integrate including processes of: drying the ceramic molded material after obtaining by cast molding; smoothing the joining surfaces of the ceramic molded materials; wetting the ceramic molded materials having smoothed joining surfaces; performing the heading joint of the joining surfaces via a slurry including the same ceramic powder as that contained in the ceramic molded material to obtain an unsintered joined body; and sintering the unsintered body to integrate.
