摘要：

The p-type skutterudite compounds of (Pr0.25Nd0.75)(x)Fe3CoSb12 (x = 0.67-0.78) have been successfully synthesized by levitation melting followed by annealing and spark plasma sintering. The thermoelectric properties have been characterized by the measurements of Seebeck coefficient, electrical conductivity and thermal conductivity in the temperature range from 300K to 850 K. The improvement in the thermoelectric properties was realized due to the reduction in the lattice thermal conductivity when the voids were partially filled by Pr0.25Nd0.75. The maximum ZT value of similar to 0.83 for (Pr0.25Nd0.75)(0.76)Fe3CoSb12 was obtained at 700 K.
