Abstract

The thermodynamic modeling of phase diagrams of the FeO‒MnO, MnO‒MgO, MnO‒Al2O3, FeO‒MgO‒MnO, FeO‒ MnO‒Al2O3, MgO‒MnO‒Al2O3 systems was carried out. The energy parameters of the theories of regular ionic solutions and subregular ionic solutions used in the simulation are determined. The calculation method used in this work allowed us to estimate the enthalpy (170,000 J/mol) and entropy (49,56 J/(mol·K)) of the formation of galaxite MnAl2O4 from the components of the oxide melt.
