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 UPDATE
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).
従来技術、競合技術の概要(英語) BACKGROUND ART
In general, materials with an increase in temperature is known to thermal expansion. Therefore, the temperature rise and the expansion of the material, the material is used as a part of the component and apparatus and the expansion, the dimension error to occur in a case where the deformation. In addition, vary depending on the material and the degree of thermal expansion, coefficient of thermal expansion of different materials in the case of the member or a combination of, for example, the semiconductor substrate is sealed with a sealing agent or a metal material the solar cell substrate to support the case, the difference between the coefficient of thermal expansion or peeling of members is sometimes warped.
On the other hand, the lattice volume decreases with an increase in temperature (having a coefficient of thermal expansion) the negative thermal expansion materials are also known. For example, perovskite-type lithium manganese oxide having a negative thermal expansion coefficient of the nitride crystal (see Patent Document 1) an inhibitor of thermal expansion has been devised.
In addition, as a material for the negative thermal expansion of the other, one in the rare earth element samarium sulfide substituted with a part of samarium element may also have been proposed (Non-Patent Document 1, Non-Patent Document 2 reference).
