Synthesis and characterization of LaMn0.5Fe0.5+xO3±δ (x = 0–0.3) perovskite-type solid solutions. Part 1: Phase formation, microstructure, and Fe2O3 surface exsolution
Perovskite-type solid solutions of LaMn0.5Fe0.5+xO3±δ (x = 0–0.3) were synthesized via the Pechini method, followed by calcination at 800 °C and characterization via a complex of physicochemical techniques. Regardless of the Fe content, solid solutions are single-phase complex oxides with a perovskite structure, as con...
