Abstract

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 (MnO2), bixbyite (Mn2O3), and hausmannite (Mn3O4) were described as stoichiometric compounds. Manganosite (Mn1−x O) was described using the compound-energy model and the liquid described using the two-sublattice model for ionic liquids.
