Original Abstract

Layered misfit cobaltites exhibit adequate combination of electrical and thermal properties under the high temperatures. Cobaltites are due to these properties and appropriate costs optimal candidates for thermoelectric industrial applications . Calcium cobaltites were prepared via conventional and less conventional synthesizing methods. Wet citric and glycine/nitrate combustion syntheses were compared with conventional solid state reaction. Prepared powders were studied in terms of phase and chemical composition, morphology, size of particles/agglomerates and thermoelectric properties. Particle size of prepared powders was varied from nano to micro size with different level of agglomeration. The lowest values of particle size (~ 160 nm) with low agglomeration were obtained with the citric combustion method. The influence of the preparation method on the properties of final bulk product was evaluated within this work.
