MANUFACTURING METHOD OF POROUS CERAMIC AND POROUS CERAMIC
To provide a manufacturing method of porous ceramic according to which a bubble is difficult to foam, the deviation of foams is suppressed, and a large number of pores of relatively small diameter are formed and porous ceramic.SOLUTION: The above problem is solved by: a manufacturing method of porous ceramic that includes a step of mixing and foaming a powdered ceramic raw material, a foaming agent, fine fibrous cellulose, and a thickener to form a bubble former, wherein the fine fibrous cellulose has an average fiber width of 3 to 100 nm; and the porous ceramic being formed through the step of forming a bubble former by mixing and foaming a powdered ceramic raw material, a foaming gent, fine fibrous cellulose and a thickener, and having a maximum value in the range of 0.1 to 1 μm in a pore diameter distribution curve.SELECTED DRAWING: Figure 4
【課題】気泡が破泡しづらく、気孔の偏りが抑制され、相対的に小径の気孔が多く形成された多孔質セラミックスの製造方法及び多孔質セラミックスを提供する。【解決手段】上記課題は、粉末状のセラミックス原料、発泡剤、微細繊維状セルロース及び増粘剤を混ぜて発泡させ気泡形成体を形成する形成工程を有し、前記微細繊維状セルロースは、平均繊維幅が３～１００ｎｍとなるものであることを特徴とする多孔質セラミックスの製造方法、及び粉末状のセラミックス原料、発泡剤、微細繊維状セルロース及び増粘剤を混ぜて発泡させ気泡形成体を形成する形成工程を経て形成され、孔径分布曲線における０．１～１μｍの範囲内に最大値を有することを特徴とする多孔質セラミックスにより解決される。【選択図】図４
