Thermodynamic Modeling of Phase Diagrams of Binary and Ternary Oxide Systems Belonging to the FeO–MgO–MnO–Al2O3 System

Thermodynamic modeling of phase diagrams of the FeO–MnO, MnO–MgO, MnO–Al 2 O 3 , FeO–MgO–MnO, FeO–MnO–Al 2 O 3 , and MgO–MnO–Al 2 O 3 systems was carried out. The energy parameters of the theories of regular ionic solutions and subregular ionic solutions used in the simulation were determined. The c...

Description
Summary:Thermodynamic modeling of phase diagrams of the FeO–MnO, MnO–MgO, MnO–Al 2 O 3 , FeO–MgO–MnO, FeO–MnO–Al 2 O 3 , and MgO–MnO–Al 2 O 3 systems was carried out. The energy parameters of the theories of regular ionic solutions and subregular ionic solutions used in the simulation were 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 formation of galaxite MnAl 2 O 4 from the oxide melt components.
