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 and EDS. An advanced version of the solid-state cell incorporating a buffer electrode was used to determine the Gibbs energies of ...
A semiquantitative Li-Mn-O phase diagram is proposed to analyze the relationship between the capacity and rechargeability of spinel Li1+2Mn2-nO4 (-0.11 less than or equal to chi less than or equal to 0.33, 0 less than or equal to y less than or equal to 0.33) as a 4 V cathode ...
Experimental data on the thermodynamics and the phase diagram of the Mn-O system were reviewed, and by application of the CALPHAD method, a consistent set of thermodynamic model parameters was optimized. The phases pyrolusite (MnO 2 ), bixbyite (Mn 2 O 3 ), and hausmannite (Mn 3 O 4 )...
Phase equilibrium in a Sm–Mn–O system has been established at 1100°C while changing the oxygen partial pressure from 0 to 13.00 in −log (PO2/atm), and a phase diagram at 1100°C is presented for a Sm2O3–MnO–MnO2 system. Under the experimental conditions, Sm2O3, MnO, Mn3O...
