THERMOELECTRIC CONVERSION MATERIAL, THERMOELECTRIC CONVERSION ELEMENT, METHOD FOR OBTAINING POWER USING THERMOELECTRIC CONVERSION MATERIAL, AND METHOD FOR TRANSPORTING HEAT

摘要

The present disclosure provides a thermoelectric conversion material having a composition represented by chemical formula Ba_1-a-b-cSr_bCa_cK_aMg₂Bi_2-dSb_d. Here, the numerical formulas 0.002 ≤ a ≤ 0.1, 0 ≤ b, 0 ≤ c, a + b + c ≤ 1, and 0 ≤ d ≤ 2 are satisfied, and the thermoelectric conversion material has a La₂O₃ type crystal structure.
