| Abstract: | The compound of Ca3Co4O9 was synthesized by traditional solid reaction method.Themicrostructures and thermoelectric properties of the ceramic were investigated by XRD,TEM,and thermoelectric property testing.Ca3Co4O9 exhibits hexagonal misfit-layered structure and lattice parameters expressed as a=5.0,c=10.7.In the range of experiment temperature Ca3Co4O9 with positive Seebeck coeffient is a p-typesemiconductor and magnitude of Seebeck coefficient and conductivity increased with increasing temperature. |
