We report the characterization of LaMnO3.15, LaCoO3 and LaFeO3 powders synthesized using a simple Pechini-type, polymerizable complex method based on polyesterification between citric acid and ethylene glycol. The microstructure was evaluated by scanning electron microscopy. Raman spectra measured at 300K, excited by a He-Ne laser were studied. Pure perovskite powders of LaMnO3.15 and LaCoO3 with rhombohedral symmetry and LaFeO3 with orthorhombic symmetry were formed at thermal treatments as low as 550°C. The mean particle size was in the nanoscale range.
