Studies on the phase relations in the system Nd-Mn-O at 1223 K showed two stable ternary compounds, NdMnO 3 and NdMn 2O 5. An isothermal section of the ternary phase diagram for the system Nd-Mn-O was constructed based on phase analysis of samples quenched after equilibration using XRPD...
Phase equilibrium was established in the system La–Mn–O at 1100°C by changing the oxygen partial pressure from 0 to 15.00 in-log (PO2/atm). A phase diagram at 1100°C in presented for the system La2O3–MnO–MnO2. Under the experimental conditions, La2O3, MnO, Mn3O4, and LaMnO...
