By the transmission electronic microscopy and X-ray powder diffraction influence of various gas environments on the perovskite – like oxides CaMnO3 microstructure synthesized by polymer-salt method was researched. Formation of the vacancy-ordered structures in the [101] direction in the samples participated in catalytic reaction of CH4 oxidation was revealed. Partial disintegration of the solid solutions was fixed at heating the sample in vacuum up to 1 100 °C.
