METHOD FOR PRODUCING POROUS SINTERED CERAMIC AND POROUS SINTERED CERAMIC
To provide a method for producing a porous sintered ceramic having both of high porosity and high strength without using hole-forming materials.SOLUTION: A method for producing a porous sintered ceramic includes the steps of molding ceramic powder with a heavy bulk density of 1.0 g/cm3 or less to give a ceramic article; forming a carbon powder-containing layer on the surface of the ceramic article to give a laminate; and irradiating the surface of the carbon powder-containing layer of the laminate with laser to form a porous sintered ceramic part.SELECTED DRAWING: Figure 1
【課題】造孔材を使用せずに、高い気孔率と高強度の両立が可能な多孔質セラミックス焼結体の製造方法を提供する。【解決手段】重装嵩密度が１．０ｇ/ｃｍ３以下のセラミックス粉末を成形して、セラミックス物品を得る工程と、前記セラミックス物品の表面に炭素粉末含有層を形成して積層物を得る工程と、前記積層物の前記炭素粉末含有層の表面にレーザを照射して、多孔質のセラミックス焼結部を形成する工程と、を含む多孔質セラミックス焼結体の製造方法である。【選択図】図１
