Abstract:

Phase equilibria in systems La-M-Fe-O (M = Ca or Sr) at 1100 degrees in air were studied. The homogeneity ranges and structures of solid solutions La1 - x M (x) FeO3 - delta (0 <= x <= 0.3 for M = Ca and 0 <= x <= 0.8 for M = Sr), Sr2 - y La (y) FeO4 - delta (0.8 <= y <= 1.0), and Sr3 - z La (z) Fe2O7 - delta (0 <= z <= 0.2) were determined using X-ray powder diffraction. The structural parameters of complex oxides were refined using the full-profile Rietveld technique. Correlations between the unit cell parameters and the compositions of solid solutions were derived. Isobaric/isothermal phase diagrams were constructed for systems La-M-Fe-O (M = Ca or Sr) at 1100 degrees C in air.
