摘要：
The samples of Cu1-xPtxFeO2 (0 <= x <= 0.05) delafossite were synthesized by solid state reaction method for studying thermoelectric properties. The properties of Seebeck coefficient, electrical conductivity and thermal conductivity were measured in the high temperature ranging from 300 to 960 K. The results of Seebeck coefficient, electrical conductivity and power factor were increased with increasing Pt substitution and temperature. The thermal conductivity was decreased from 5.8 to 3.5 W/mK with increasing the temperature from 300 to 960 K. An important results, the highest value of power factor and ZT is 2.0 x 10(-4) W/mK(2) and 0.05, respectively, for x = 0.05 at 960 K. (C) 2011 Elsevier B.V. All rights reserved.
