This work investigated the synthesis and characterization of a perovskite material based on the La 0.95 Sr 0.05 CrO3 system, by a wet chemical route that involves the combustion-polymerization method, using citric acid as complexing agent, in order to obtain intermediate coordination species, which evolve depending on the temperature until the desired consolidation crystalline phase is obtained. The metal-organic precursor characterization was performed by thermal analyses (TGA-DTA), in order to evaluate an ideal consolidation temperature of the searched crystalline phase. The analysis by the X-ray di ffraction (XRD), the transmission electron microscopy (TEM), the X-ray fluorescence microprobe (EDX) and the surface
