“…The optimized MgO-P 2 O 5 phase diagram and its calculated P 2 O 5 (l) and MgO(l) activities are presented in Figures 4 and 5, respectively, with experimental data [20,[29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44]. In a similar way, all the available experimental data concerning the phase diagram and thermodynamic properties of all other binary MgO-, FeO-, Fe 2 O 3 -, MnO-, Al 2 O 3 -, Na 2 O-and SiO 2 -P 2 O 5 systems were critically evaluated and optimized to obtain the binary interactions between the oxide component and P 2 O 5 in liquid slag.…”

The Na 2 O-MgO-CaO-FeO-Fe 2 O 3 -Al 2 O 3 -SiO 2 -P 2 O 5 system is a basic oxide system for the Basic Oxygen Furnace (BOF) process as well as the hot metal dephosphorization process. Numerous experimental investigations on this oxide system are being carried out to find out an advanced process route for P removal from molten iron. In spite of their industrial importance, however, phase equilibria in oxide systems containing P 2 O 5 have not been well investigated due to the complexity of their chemistry. No systematic thermodynamic modeling of these systems has been conducted to date, either. In order to meet the strong demands of steelmaking and other industries, new systematic thermodynamic modeling of the P 2 O 5 -containing oxide systems (Na 2 O-MgO-CaO-FeO-Fe 2 O 3 -Al 2 O 3 -SiO 2 -P 2 O 5 ) and key phase diagram experiments have been carried out over the past years. In the present study, the results of the thermodynamic modeling of unary, binary and ternary P 2 O 5 -containing systems and the applications of the thermodynamic database to the dephosphorization by multi-component slag in BOF process are presented in comparison with experimental data. All thermodynamic calculations were performed using FactSage thermodynamic software.
