Abstract:: Abstract: Thermoeleetrie materials Ca3Co4O9 doped with Y in the composilion of Y0.2Ca2.8Co4O9 were prepared by sol-gel method combined high - pressure compacting technique followed by pressureless sinteringThe mierostruetures of the oxides were investigated and the eleetrical properies ( including of Seebeck coelfieient and eleetrieal conduetivity) were measured from room temperature to 1000 K. lt was found that highpressure compacling helps to improve the density and texture of Ca3Co4o9 . The eleelrical resistivity deereaseswith an inerease of temperalure, while the Seebeck eoelficient inereases with an inerease of temperature. Themaximum power factor 3.9 pW/emK2 at 973K is obtained for the sample pressed by high pressure.
