Beschreibung
Zusammenfassung:	A method of fabricating a ceramic molded body for sintering, which includes molding a raw material powder containing a ceramic powder and a thermoplastic resin having a glass transition temperature higher than room temperature into a predetermined shape by isostatic pressing and in which a raw material powder slurry is prepared by adding the ceramic powder and the thermoplastic resin to a solvent so that the thermoplastic resin is 2% by weight or more and 40% by weight or less with respect to a total weight of the ceramic powder and the thermoplastic resin, a cast-molded body is formed by wet-casting the raw material powder slurry into a predetermined shape, dried, and subjected to first-stage isostatic press molding at a temperature lower than the glass transition temperature of the thermoplastic resin to form a first-stage press-molded body, then this first-stage press-molded body is heated to a temperature equal to or higher than the glass transition temperature of the thermoplastic resin, and warm isostatic press (WIP) molding is performed as second-stage isostatic press molding to fabricate a ceramic molded body.
