摘要：

The phase equilibria in the LaCoO(3)-LaMnO(3)-SrCoO(2.5)-SrMnO(3) system were studied at 1100 degrees C in air. The existence of SrCo(1-y)Mn(y)O(3-delta) with the homogeneity range 0.45 less than or equal to y less than or equal to 0.55 was confirmed. The homogeneity range of solid solutions of general formula La(1-x)Sr(x)Co(1-y)Mn(y)O(3+/-delta) with orthorhombic, rhombohedral, and cubic structure has been determined. Based on the experimental results and earlier data, the pseudoquaternary phase diagram was constructed. (C) 1999 Elsevier Science Ltd.
