Abstract

In this work, CuGdO2 were prepared through the sintering of mixtures of CuO and Gd2O3 powders at 1373 K. The Seebeck coefficient and electrical resistivity were measured by ZEM-3 series in low pressure helium gas atmosphere at temperature ranges of 325520 K. The result shown that, electrical resistivity and power factor decrease with increasing of temperature while the power factor show the opposite trend. The power factor was calculated by P=S2/ (where S is Seebeck coefficient and  is electrical resistivity) and The highest value obtained for the power factor was 4.47 W1m1K2 at 520 K.
