METHOD OF MANUFACTURING TYPE-I CLATHRATE COMPOUND, THERMOELECTRIC CONVERSION MATERIAL AND THERMOELECTRIC CONVERSION ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method by which a type-I clathrate compound represented by a composition formula Ba₈(Ga, Sn)₄₆ can be stably synthesized, and to provide a thermoelectric conversion material that is made of the type-I clathrate compound with a high Seebeck coefficient synthesized by the manufacturing method, as well as a thermoelectric conversion element using the thermoelectric material.;SOLUTION: The method is used to manufacture a type-I clathrate compound as follows: a material compound (excluding type-I clathrate compound) represented by a composition formula Ba₈(Ga_x, Sn_1-x)₄₆ (0x1) is heated in a range between 500°C and 750°C, so as to make the type-I clathrate compound represented by the composition formula.;COPYRIGHT: (C)2009,JPO&INPIT
