Introduction Lanthanum Cobaltites doped with alkali earth elements (Ca, Sr, Ba) exhibit unique properties and are considered as promising materials for numerous applications such as catalysts for various oxidation-reduction reactions, oxygen permeable membranes or electrodes for different electrochemical devices such as solid oxide fuel cells [1].
Lately, strontium-doped lanthanum cobaltites have been proposed as a cathode material in intermediate temperature SOFCs, due to their high electronic conductivity at intermediate operating temperatures [2,3].
Several wet chemical synthesis techniques have been applied, instead of solid state reactions, for the synthesis of lanthanum cobaltites of high purity and controlled microstructure as the actual composition and the properties of these materials strongly depend on the preparation method. [4, 5] Moreover, using fine particles is regarded as a promising way to improve the homogeneity and sinterability of the powders and achieve the desirable properties.
