Abstract
Lanthanum-transition metal mixed oxides, with the general formula La1−x M x BO3, have been prepared, whereinM stands for Ca and Sr, andB stands for one or more transition metals selected from the group consisting of Cr, Mn, Fe, Co and Ni, where 0⩽x⩽0.50. A drip pyrolysis method has been developed to synthesize the mixed oxides at low temperature (550‡C). As combustion fuel, glucose was added to the aqueous solution of metal salts. The prepared compounds have perovskite structures. This paper examines the possibilities of finding a simple and large scale procedure in order to produce a long list of perovskites necessary for fuel cell materials (air electrode and interconnect) and catalysts for oxidation catalysis. X-ray diffraction (XRD) analysis, scanning electron microscope (SEM) measurements and determination of specific surface area, carbon content and particle size distribution have been carried out on the obtained perovskite powders.
