Abstract: The electrical conductivity and Seebeck coefficients of AgSbO3 with a defect pyrochlore structure were investigated for evaluation as thermoelectric material. In sintering AgSbO3, CuO was used as a sintering aid, and Cu substituted for Ag in the ceramic during the sintering. AgSbO3 is an n-type semiconductor, and the addition of Cu increased electrical conductivity and decreased the absolute value of the Seebeck coefficient. The power factor of the 2.5% CuO-added sample was 7.24×10-4 Wm-1 K-2 at 800°C. This value is one of the highest observed in oxide materials.
