  • Abstract
    The nanosized Ca9Co12O28 powder was synthesized via a sol-gel process. The phase composition was characterized by means of X-ray diffraction. Polycrystalline samples of Ca9Co12O28 were prepared by a sintering procedure of nanosized power. The Seebeck coefficient and electrical conductivity of the samples were measured from 573K up to 1073K. The Seebeck coefficient increases with increasing temperature
