Abstract :
The phase equilibria in the LaCoO3–LaMnO3–SrCoO2.5–SrMnO3 system were studied at 1100°C in air. The existence of SrCo1−yMnyO3−δ with the homogeneity range 0.45 ≤ y ≤ 0.55 was confirmed. The homogeneity range of solid solutions of general formula La1−xSrxCo1−yMnyO3±δ with orthorhombic, rhombohedral, and cubic structure has been determined. Based on the experimental results and earlier data, the pseudoquaternary phase diagram was constructed.
