摘要：

Thermoelectric properties of skutterudites FexNiyCo1-x-ySb3 (x=y=0, 0.125, 0.25, 033, 0.375) have been reported. FexNiyCo1-x-ySb3 pounds were synthesized by direct reactions between the elements. Both p-type and n-type thermoelectric materials can be obtained in FexNiyCo1-x-ySb3 system. The electrical conductivity measurements showed typical semiconductor behavior. The values of thermal conductivity at room temperature were substantially reduced from 9 to 3 W m(-1) K-1 by the substitution of Fe and Ni for Co in CoSb3. The highest figure of merit (ZT) of 0.16 is obtained for Fe0.375Ni0.375Co0.25Sb3 at 610K. (c) 2006 Elsevier B.V. All rights reserved.
