MAGNESIUM-BASED THERMOELECTRIC CONVERSION MATERIAL, MAGNESIUM-BASED THERMOELECTRIC CONVERSION ELEMENT, AND METHOD FOR PRODUCING MAGNESIUM-BASED THERMOELECTRIC CONVERSION MATERIAL
A magnesium-based thermoelectric conversion material (11) made of a sintered compact of a magnesium compound, in which, in a cross section of the sintered compact, a Si-rich metallic phase (15) having a higher Si concentration than in magnesium compound grains is unevenly distributed in a crystal grain boundary between the magnesium compound grains, an area ratio of the Si-rich metallic phase (15) is in a range of 2.5% or more and 10% or less, and a number density of the Si-rich metallic phase (15) having an area of 1 µm2or more is in a range of 1,800 /mm2or more and 14,000 /mm2or less.
