摘要/Abstract

Abstract: TiCoSb-based half-Heusler compounds with the substitution of Zr for Ti have been prepared quickly by combining high- nergy ball milling method with spark plasma sintering technique, and their thermal transport properties have been investigated. With the increase of the concentration of Zr, the thermal conductivity of Ti$_{1 - x}$Zr$_{x}$CoSb compounds decreases significantly. Compared with the thermal conductivity of TiCoSb compound, that of Ti$_{0.5}$Zr$_{0.5}$CoSb decreases by 107% at 1000 K.

Key words: thermoelectric, half-Heusler compounds, thermal conductivity
