Preparation of AgSbO₃ ceramics by tartrate process and their thermoelectric properties

Abstract

AgSbO₃ ceramics were prepared by solid state reactions and tartrate processes. And their electrical conductivity and Seebeck coefficient were measured. Sb excess made lattice constants large and Ag excess make Ag metal deposition. Tartrate process of CuO-added AgSbO₃ made electrical conductivity high and absolute value of Seebeck conductivity low, which was explained by homogeneity of powders prepared by tartrate process and substitution of Cu for Ag site was efficient.
