METHOD FOR PREPARING CERAMIC MOLDED BODY FOR SINTERING AND METHOD FOR PRODUCING CERAMIC SINTERED BODY
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 first-stage press-molded body is fabricated by subjecting a uniaxially press-molded body fabricated by uniaxially pressing the raw material powder into a predetermined shape or the raw material powder filled in a rubber die to a first-stage isostatic press molding at a temperature lower than a glass transition temperature of the thermoplastic resin and then a ceramic molded body is fabricated by heating this first-stage press-molded body to a temperature equal to or higher than the glass transition temperature of the thermoplastic resin and performing warm isostatic press molding as second-stage isostatic press molding.
