Abstract
LaMnO3 specimens were synthesized with using of different precursors on X-ray diffractometer (method in situ). It was established that the cubic nano- and microcrystalline perovskite phases starts to form in the temperature range 400-600°C. Synthesized LaMnO3 specimens at room temperature have stoichiometric and nonstoichiometric perovskite-type phases of different symmetry: Pnma (solid state synthesis) and R 3 c (wet methods of precursors’ preparation – sorption, co-precipitation and sol-gel)
