Abstract AITranslate

The thermodynamic assessment of an Al2O3–MnO pseudo-binary system has been carried out with the use of an ionic model. The use of the electro-neutrality principles in addition to the constitutive relations, between site fractions of the species on each sub-lattice, the thermodynamics descriptions of each solid phase has been determined to make possible the solubility description. Based on the thermodynamics descriptions of each phase in addition to thermo-chemical data obtained from the literature, the Gibbs energy functions were optimized for each phase of the Al2O3–MnO system with the support of PARROT®module from ThemoCalc®package. A thermodynamic database was obtained, in agreement with the thermo-chemical data extracted from the literature, to describe the Al2O3–MnO system including the solubility description of solid phases.
