Fast preparation and thermal transport property of TiCoSb-based half-Heusler compounds

Year: 2007

Type: article

Abstract: TiCoSb-based half-Heusler compounds with the substitution of Zr for Ti have been prepared quickly by combining high-energy 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 200% at 1000 K.
