N2 - Ca3Co4O9 is a p-type semiconductor and a promising thermoelectric material with misfit layer structure. Cobalt-based layered structure materials have been studied as thermoelectric material candidates because of their nontoxicity, light weight, high thermal and chemical stability and oxidation resistance at high temperature. The operating area of Ca3Co4O9 in thermoelectric applications is roughly from 800K to 1000K. Ca3Co4O9 powders were synthetized by a sol-gel method which enables fabrication of high purity and homogeneous particles. Calcium and cobalt nitrate hydrates were used as feedstock and citric acid as complexing agent in the sol-gel procedure. Powders were calcinated at 1123K and further processing by ball milling. Pure Ca3Co4O9 powders were sintered by SPS and conventional method.
