CERAMIC ARTICLE MANUFACTURING METHOD AND CERAMIC ARTICLE
To provide a method for manufacturing a shaped ceramic article having a porous portion with improved mechanical strength while obtaining high modeling accuracy, as well as a ceramic article prepared by the method.SOLUTION: A method for manufacturing a ceramic article, comprising (i) a step of levelling powder of a metal oxide consisting mainly of aluminum oxide and forming a powder layer, (ii) a step of irradiating the powder layer with an energy beam based on the shaping data so as to melt, solidify or sinter the powder, (iii) a step of absorption in which a shaped article having a porous portion formed by repeating the steps (i) and (ii) is allowed to absorb a liquid that contains a zirconium component, and (iv) a step for heating the shaped article containing the zirconium component absorbed therein, wherein the step of absorbing the liquid is carried out in such a manner that the ratio of the zirconium component contained in the porous portion of the shaped article is 0.3 to 2.0 mol%, based on metallic components contained therein.SELECTED DRAWING: None
【課題】高い造形精度を得ながら造形物の機械的強度の向上を実現した多孔質部を有するセラミックス物品の製造方法、及びセラミックス物品を提供する。【解決手段】（ｉ）酸化アルミニウムを主成分とする金属酸化物の粉末を均し、粉末層を形成する工程と、（ｉｉ）粉末層に造形データに基づいてエネルギービームを照射し、粉末を熔融及び凝固、または焼結させる工程と、（ｉｉｉ）工程（ｉ）及び工程（ｉｉ）を繰り返して形成した、多孔質部を有する造形物にジルコニウム成分を含有する液体を吸収させる工程と、（ｉｖ）ジルコニウム成分を含有する液体を吸収させた造形物を加熱する工程と、を有し、吸収工程において、多孔質部に含まれる金属成分におけるジルコニウム成分の割合が０．３ｍｏｌ％以上２．０ｍｏｌ％以下となるように吸収工程で液体を吸収させる。【選択図】なし
