Year: 2013

Type: article

Abstract: Pure Ca2.6Bi0.4Co4O9Ceramic compound were successfully prepared by adopting a facile solution combustion synthesis method. The crystallinity, morphology were characterized by XRD, FE-SEM. The thermoelectric properties of Bi-doped Ca3Co4O9were also systematically investigated. The results indicate the prepared samples are p-type semiconductors. Both the electrical conductivity and the Seebeck coefficient increase with the increasing of temperatures. Bi substitutions at Ca site enhanced carrier mobility and resulted in a marked increase in thermoelectric properties. The power factor of as-prepared Ca2.6Bi0.4Co4O9sample can reach 2.67×10-4W/mK2at 1000 K. The synthesized Ca2.6Bi0.4Co4O9ceramic materials have potential application for high-temperature thermoelectric energy conversion.
