発明の名称 (英語) METHOD FOR PRODUCING SAMARIUM MONOSULFIDE, VOLUME CHANGE MATERIAL, VOLUME CONTROL MEMBER, NEGATIVE THERMAL EXPANSION MATERIAL, AND COMPOUND MATERIAL
発明の概要(英語) A method for producing samarium monosulfide according to one embodiment of the present invention comprises: a step for forming a solid solution of a rare earth sesquisulfide by heating, as starting materials, samarium sulfide and a sulfide that contains a rare earth element other than samarium, and firing the starting materials within the temperature range of from 500°C (inclusive) to 1,200°C (exclusive), said rare earth sesquisulfide being obtained by substituting some of samarium by a rare earth element; and a step for producing samarium monosulfide in the form of a solid solution by mixing the solid solution of a rare earth sesquisulfide and samarium with each other, and heating the mixture within the temperature range of from 500°C (inclusive) to 1,200°C (exclusive).
