THERMOELECTRIC MATERIAL AND THERMOELECTRIC MODULE
PROBLEM TO BE SOLVED: To provide a thermoelectric material having an excellent thermoelectric property, which enables the increase in electric conductivity or the reduction in thermal conductivity.SOLUTION: A thermoelectric material comprises at least Cr and Si as primary components. The thermoelectric material further comprises an element (A) which at least belongs to the same group as Cr, and is larger than Cr in atomic weight; and the element (A) is Mo or W. The thermoelectric material further comprises: an element (B) of which the compound with Si has a crystal structure of the same form as the crystal structure of a compound of Cr and Si; the element (B) is larger than Cr in atomic weight; and the element (B) is Nb or Ta.SELECTED DRAWING: Figure 2
【課題】電気伝導率を大きくすること、あるいは、熱伝導率を小さくすることが可能な、優れた熱電特性を有する熱電材料を提供する。【解決手段】少なくともＣｒ及びＳｉを主成分とする熱電材料において、熱電材料は、少なくともＣｒの同族元素であり、かつ、Ｃｒよりも原子量が大きい元素（Ａ）を含有する。元素（Ａ）はＭｏあるいはＷである。Ｓｉとで構成される化合物の結晶構造が、ＣｒとＳｉとで構成される化合物と同形の結晶構造を有し、かつ、Ｃｒよりも原子量が大きい元素（Ｂ）を含有する。元素（Ｂ）はＮｂあるいはＴａである。【選択図】図２
