METHOD FOR MANUFACTURING CERAMIC MOLDING FOR SINTERING AND METHOD FOR MANUFACTURING CERAMIC SINTERED BODY
To provide a method for manufacturing a ceramic molding for sintering capable of manufacturing a ceramic sintered body which has various characteristics such as an extremely small residual gap, no residual stress, is dense and good.SOLUTION: A method for manufacturing a ceramic molding for sintering which performs hydrostatic pressurization using ceramic powder and raw material powder containing a thermoplastic resin having a glass transition temperature higher than room temperature to mold the powder into a predetermined shape, and includes applying first-stage hydrostatic pressurization to a uniaxially-pressed molding obtained by uniaxial pressing the raw powder into a predetermined shape or the raw powder filling a rubber die into a predetermined shape at a temperature lower than a glass transition temperature of the thermoplastic resin and manufacturing first-stage press-molded body; and heating the first-stage press-molded body to a temperature equal to or higher than a glass transition temperature of the thermoplastic resin, applying hot hydrostatic pressurization molding to the first-stage press-molded body as second-stage hydrostatic pressurization, and manufacturing a ceramic molding.SELECTED DRAWING: None
【課題】残存空隙が極めて小さく、残留応力もない、緻密で良好な各種特性を有するセラミック焼結体を作製することのできる焼結用セラミックス成形体の作製方法を提供する。【解決手段】セラミックス粉末とガラス転移温度が室温より高い熱可塑性樹脂とを含む原料粉末を用いて静水圧加圧して所定形状に成形する焼結用セラミックス成形体の作製方法であって、前記原料粉末を所定形状に一軸プレスした一軸プレス成形体を、又はゴム型に充填した前記原料粉末を前記熱可塑性樹脂のガラス転移温度よりも低い温度で第1段の静水圧加圧成形して第1段加圧成形体を作製し、次いでこの第1段加圧成形体を前記熱可塑性樹脂のガラス転移温度以上に加熱して第2段の静水圧加圧成形として温間静水圧加圧成形を行ってセラミックス成形体を作製する。【選択図】なし
