THERMOELECTRIC CONVERSION MATERIAL, THERMOELECTRIC CONVERSION ELEMENT, AND THERMOELECTRIC CONVERSION MODULE
This thermoelectric conversion material is characterized by being composed of a sintered body of a compound that contains a dopant, and is also characterized in that the standard deviation of the dopant concentration as calculated by measuring the dopant concentration of each one of a plurality of compound particles observed in a cross-section of the sintered body is 0.15 or less. It is preferablethat the compound is composed of one or more compounds which are selected from among MgSi compounds, MnSi compounds, SiGe compounds, MgSiSn compounds and MgSn compounds.
本发明的热电转换材料的特征在于，由含有掺杂剂的化合物的烧结体构成，并且针对在所述烧结体的截面中观察到的多个化合物粒子，测量每个化合物粒子的掺杂剂浓度，计算出的所述掺杂剂浓度的标准偏差设为0.15以下。在此，所述化合物优选为选自MgSi系化合物、MnSi系化合物、SiGe系化合物、MgSiSn系化合物、MgSn系化合物中的一种或两种以上。
