PRODUCTION METHOD OF CERAMIC MOLDED ARTICLE AND PRODUCTION METHOD OF CERAMIC SINTERED COMPACT
PROBLEM TO BE SOLVED: To provide a production method of a ceramic molded article by which a density distribution can be made uniform.SOLUTION: The production method of a ceramic molded article comprises compression-molding a raw material powder comprising a ceramic powder; and the method includes a molding step of adding at least one kind of liquid having a viscosity of 2.0 mPa s or more and 5000 mPa s or less at 20°C and containing solid particles of an organic substance dispersed in a colloidal state, as a molding assistant, to the raw material powder, then charging a mold with the raw material powder, and press-molding the powder.SELECTED DRAWING: None
【課題】密度分布を均一化できるセラミックス成形体の製造方法を提供する。【解決手段】セラミックス粉末を含有する原料粉末を圧縮成形するセラミックス成形体の製造方法であって、成形助剤として、２０℃での粘度が２．０ｍＰａ・ｓ以上５０００ｍＰａ・ｓ以下で、有機物の固体粒子がコロイド状に分散した少なくとも１種の液体を前記原料粉末に添加し、前記原料粉末を金型に充填してプレス成形する成形工程を備えるセラミックス成形体の製造方法。【選択図】なし
