Title:
THERMOELECTRIC CONVERSION MATERIAL, COMPOSITION FOR THERMOELECTRIC CONVERSION MATERIAL, THERMOELECTRIC CONVERSION ELEMENT, THERMOELECTRIC CONVERSION MODULE, AND METHOD FOR PRODUCING THERMOELECTRIC CONVERSION MATERIAL
Document Type and Number:
WIPO Patent Application WO/2022/259758
Kind Code:
A1
Abstract:
This thermoelectric conversion material is a p-type thermoelectric conversion material that includes carbon and in which the main phase is an alloy containing Mg and Bi. The thermoelectric conversion material is, for example, a thermoelectric conversion material having a Mg3(Sb, Bi)2-based alloy as a main phase, and the atomic percentage of Bi included in the main phase is equal to or greater than the atomic percentage of Sb included in the main phase. The thermoelectric conversion material satisfies, for example, the following mathematical expression (M1): 0.01 at% ≤ CC ≤ 1.2 at%. CC represents the content of carbon in the thermoelectric conversion material.
