Abstract: XRD, SIMS, BET, MDPD, TPR, and HREM were used to study the effect of time of mechanical treatment (MT) of the mixture of simple La2O3, CaO and Fe2O3 oxides and the temperature of subsequent calcination on the phase composition, real structure and catalytic properties of substituted La1-x CaxFeO3-0.5x (0 ≤ x ≤ 1) perovskites in CO catalytic oxidation. The phase composition and microstructure of MT samples differ significantly from those of ceramic samples: no Grenier phase La0.33Ca0.67FeO2.67 were and micro-heterogeneous solid composite La0.5Ca0.5FeO2.75 found in ceramic samples; independently of the time of treatment and Ca content, the MT samples are composed of the perovskite and brown mille rite phases. The microstructure of MT samples (Tcalc < 1100 °C)
