METHOD OF PRODUCING THERMOELECTRIC CONVERSION MATERIAL USING SOLVOTHERMAL METHOD

摘要

PROBLEM TO BE SOLVED: To provide means for producing a thermoelectric conversion material of small grain size effectively.SOLUTION: A method of producing a thermoelectric conversion material containing at least one kind of element A and at least one kind of element B includes a solvothermal step for causing solvothermal reaction of at least one kind of element A selected from a group consisting of i and Sb, and at least one kind of element B selected from a group consisting of Tem Se and S, in an organic solvent having a polarity parameter of Snyder exceeding 4.3.SELECTED DRAWING: Figure 2
