| Abstract | The metal stoichiometry ranges of the Ln2 − xMnxO3 ± δ (Ln = Y, Ho, Er) manganites have been determined using X-ray diffraction analysis of ceramic samples prepared by reacting oxide mixtures in air at temperatures from 900 to 1400°C. The results are represented as partial phase diagrams of the Ln-Mn-O systems in air. Comparison of the phase diagrams demonstrates that the phase boundaries of the manganites are determined not only by the effective cation radius of the rare-earth metal. The solubilities of the binary oxides Y2O3, Ho2O3, and Mn3O4 in yttrium and holmium manganites increase with temperature, with significant quantitative distinctions. The Er2O3 and Mn3O4 solubilities in erbium manganite remain unchanged over the entire temperature range studied. The LnMn2O5 solubility in LnMnO3 ± δ is an intricate function of temperature. We analyze the possible causes of the Ln2O3, Mn3O4, and LnMn2O5 solubility in the LnMnO3 ± δ (Ln = Y, Ho, Er) manganites. |
