CERAMIC SINTERED BODY AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a ceramic sintered body having reduced deterioration of strength derived from juncture of ceramic molded bodies each other and to provide a manufacturing method thereof.SOLUTION: (1) A plurality of ceramic molded bodies C1 and C2 are prepared. (2) A groove G is formed in at least one of the plurality of ceramic molded bodies C1 and C2 so that it is located continuously from a joint region of the ceramic molded bodies C1 and C2 to a boundary of the joint region. (3) Slurry S is attached to the joint region of the plurality of ceramic molded bodies C1 and C2. (4) A joint molded body C is obtained by jointing the plurality of ceramic molded bodies C1 and C2 at the joint region. (5) The joint molded body C is integrated by sintering.
