摘要
PROBLEM TO BE SOLVED: To provide a Heusler type iron-based thermoelectric material which is improved in electrothermal characteristics by suppressing the rise in an electric resistivity ρ and lowering a thermal conductivity κ.;SOLUTION: A thermoelectric material comprises: a base material having crystal grains including an Fe2 VAl based Heusler compound represented by the formula (1) below; and Cu phases distributed in the crystal grains. (Fe1-aM1a)2-x-y(V1-bM2b)1+x(Al1-cM3c)1+y Formula(1), where M1 is at least one element selected from a group consisting of 3d, 4d, 5d transition metal elements (except Fe), M2 is at least one element selected from a group consisting of 3d, 4d, 5d transition metal elements (except V), M3 is at least one element selected from a group consisting of elements of Group IIIb (except Al), Group IVb (except C), Group Vb (except N); a≤0.2, b≤0.4, c≤0.4, |x|≤0.2, and |y|≤0.2.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
