Year: 2013

Type: article

Abstract: We present characterization and thermoelectric properties of oxide thermoelectric materials of P-Ca3Co4O9 and N-CaMnO3 synthesized by solid state reaction method and sintering in air. The crystalline structure was measured by x-ray diffraction (XRD) and confirmed by transmission electron microscope (TEM). The powder size and gran size of P-Ca3Co4O9 and N-CaMnO3 were observed by scanning electron microscope (SEM). The electrical resistivity and Seebeck coefficient are measured. It was found that, the P-Ca3Co4O9shows the point symmetry groups in three dimensions require of monoclinic system and N-CaMnO3 shows cubic system corresponding with TEM results. The powder size and grain size were obtained mean values of 1-3 µm. The electrical resistivity and Seebeck coefficient were obtained for P-Ca3Co4O9and for N-CaMnO3 at 360 K.
