Composite material of complex alloy and generation method thereof, thermoelectric device and thermoelectric module

Abstract

A composite material of complex alloy is provided and it is the Ceramic-Metal Composite based on a thermoelectric material filled with ceramic material. The composite material is represented by the following general formula (I). A1−xBx   (I) In the general formula (I), 0.05≦X≦0.2; A represents a Half-Heusler thermoelectric material and its proportional composition is represented with the following formula (II). (Tia1Zrb1Hfc1)1−y−zNiy Snz   (II) In the general formula (II), 0<a1<1, 0<b1<1, 0<c1<1, a1+b1+c1=1, 0.25≦y≦0.35, and 0.25≦z≦0.35; B represents at least one element selected from a group of C, O, and N.
