MAGNESIUM SILICIDE, THERMOELECTRIC CONVERSION MATERIAL, SINTERED BODY, SINTERED BODY FOR THERMOELECTRIC CONVERSION ELEMENT, THERMOELECTRIC CONVERSION ELEMENT, AND THERMOELECTRIC CONVERSION MODULE

摘要

Provided is a novel material containing a dopant having good compatibility with magnesium silicide. Co, Nb, Nd, Sm, Ta, and Zn are used as the dopant for doping the magnesium silicide. The amount of dopant contained in this magnesium silicide is not particularly limited, but the dopant content, as an atomic ratio, is preferably 0.10-2.00 at%. Also, a sintered body obtained by sintering this magnesium silicide can be ideally used as a thermoelectric conversion element.
