摘要：
The Al2O3-FeO-Fe2O3-MgO-TiO2-Ti2O3 system has been thermodynamically assessed using all available experimental data. Titanium was introduced into the thermodynamic description of the liquid phase as well as of solid solution phases such as MeO, Cubic Spinel, Titania Spinel, Corundum and Pseudobrookite. Particular attention was given to the phase Cubic Spinel which forms a wide miscibility range amongst Fe3O4-TiFe2O4 TiMg2O4-TiMn2O4. In addition, the present modelling of the phase Pseudobrookite allows the description of the experimentally determined mutual solubility between Al2TiO5, MgTi2O5, FeTi2O5, Fe2TiO5 and Ti2O5. 9 titanates as stoichiometric phases have also been included in the database.
