High-temperature stability, structure and thermoelectric propertiesof CaMn1-xNbxO3 phases

Original language description

Polycrystalline perovskite-type CaMn1-xNbxO3 phases (with x = 0.02, 0.05, 0.08 and 0.10) were investigated with regard to their structure, microstructure and thermal stability as a function of temperature. A possible mechanism relating the high-temperature structural transition and the thermal reduction process of slightly substituted CaMnO3 phases was proposed. The thermal reduction process resulted in a change in the Mn3+/Mn4+ concentrations in the Mn sublattice, and therefore in a modification of thetransport properties. A comprehensive study examined the impact of both phenomena on the electrical and thermal transport properties.
