PRODUCTION METHOD OF CYLINDRICAL CERAMIC SINTERED BODY
To provide a production method of a cylindrical ceramic sintered body which has small deformation on sintering and has a stable shape after repeated firing.SOLUTION: The production method of a cylindrical ceramic sintered body by firing a cylindrical ceramic molding using a firing furnace includes: a molding step S1 of filling raw material powder in a cavity of a cylindrical molding die, followed by press-molding to give a cylindrical ceramic molding; an arrangement step S2 of arranging the cylindrical ceramic molding in the firing furnace; and a firing step S3 of firing the arranged cylindrical ceramic molding in the firing furnace to give a cylindrical ceramic sintered body. In the arrangement step S2, a plurality of first supporting members provided with a plurality of ridge parts on a top face are arranged on a furnace bottom of the firing furnace or on a bottom plate installed on the furnace bottom, a columnar second supporting member is placed on the first supporting members, and the cylindrical ceramic molding is placed standing straight on the second supporting member.SELECTED DRAWING: Figure 1
【課題】焼結時における変形が少なく、繰り返し焼成を行っても安定した形状を有する円筒形セラミックス焼結体の製造方法を提供することを目的とする。【解決手段】焼成炉を用いて円筒形セラミックス成形体を焼成する円筒形セラミックス焼結体の製造方法であって、円筒形成形型のキャビティ内に原料粉末を充填し、加圧成形して円筒形セラミックス成形体を得る成形工程Ｓ１と、円筒形セラミックス成形体を焼成炉内に配置する配置工程Ｓ２と、配置した円筒形セラミックス成形体を焼成炉において焼成して円筒形セラミックス焼結体を得る焼成工程Ｓ３とを有し、配置工程Ｓ２では、焼成炉内の炉床あるいは炉床の上に設置した敷板に、上面に複数の凸条部を有する第１の支持部材を複数並べ、該第１の支持部材の上に柱状の第２の支持部材を載置し、該第２の支持部材上に円筒形セラミックス成形体を直立させた状態で載置する。【選択図】図１
