La1-xSrxMnO3 ± d (x = 0.15, d 0) and La1-xSrxCrO3 ± d (x= 0.2, d 0) powders were synthesized by drip/spray pyrolysis of solutions of analysed metal nitrate mixtures, with added chelating ligands and solvents. The solutions were dripped or sprayed into a rotating tube furnace at 600-700 oC, resulting in homogeneous single phased ceramic powders. X-ray diffraction diagrams were taken using copper Ka radiation with a Bragg-Brentano diffractometer. The obtained X-ray diagrams of the synthesised La0.85Sr0.15MnO3±d and La0.8Sr0.2CrO3±d (d 0) powders were compared to data in the literature which was reviewed. The structure, lattice parameters, etc., of the resulting phases do not depend very much on the kind of chelating agent but on the metal composition and the history of the sample.
