METHOD FOR PRODUCING SINTERED BODY AND SINTERED BODY

YAMAMOTO RYO / TAKETOMI SHOZO

A method for producing a sintered body includes: providing a raw material mixture containing oxide particles containing Ce, Al, Ga, optionally Sc, and a rare earth element R¹ being at least one selected from the group consisting of Y, La, Gd, and Tb to obtain a target composition, wherein a total molar ratio of R¹ and Ce is 3, and a molar ratio of Ce, a total molar ratio of Al, Ga, and Sc, a molar ratio of Al and a molar ratio of the Ga are as described in the disclosure; molding the raw material mixture to obtain a molded body; and calcining the molded body to obtain a sintered body containing a rare earth aluminate crystal phase and 2.7% by volume or more to 57.0% by volume or less of an aluminum oxide phase.
