Abstract
The sequence of phase transformations responsible for the dissociation of the compounds NdMn2O5 and NdMnO3 in the Nd-Mn-O system has been identified by a static technique at a reduced oxygen pressure in combination with thermal analysis and high-temperature X-ray diffraction. We have mapped out the p-T-x (oxygen pressure-temperature-composition) phase diagram of the Nd-Mn-O system and determined the thermodynamic characteristics of formation of the compounds NdMn2O5 and NdMnO3 from their constituent elements.
