THERMOELECTRIC PROPERTIES OF CERMET Bi2Te3–Gd COMPOSITE

Year: 2022

Type: article

Abstract: The aim of this paper is exploring an opportunity to improve the thermoelectric properties of the cermet Bi2Te3 + 0.5 at. % Gd composite. It was found that under spark plasma sintering, a composite microstructure consisting of the Ni inclusions, which are randomly distributed inside the grained Bi2Te3 matrix, is really formed. With introducing Ni inclusions in Bi2Te3, the specific electrical resistivity increases, and the total thermal conductivity decreases. The highest thermoelectric figure-of-merit for the composite (~ 0.63) happened to be slightly enhanced as compared to that for the matrix material (~ 0.58).
