AbstractA thermodynamic model for calculating the mass action concentrations of structural units in CaOSiO2MgOFeOMnOAl2O3CaF2 slags, i.e., the IMCT-Ni model, has been developed based on the ion and molecule coexistence theory (IMCT). The calculated comprehensive mass action concentration of iron oxides $N_{{\rm Fe}_{t} {\rm O}} $ has been compared with the reported activity of iron oxide $a_{{\rm Fe}_{t} {\rm O}} $ in 14 FeO-containing slag systems from literatures. The good agreement between the calculated $N_{{\rm Fe}_{t} {\rm O}} $ and reported $a_{{\rm Fe}_{t} {\rm O}} $ indicates that the developed IMCT-Ni model can be successfully applied to predict the activity of iron oxide $a_{{\rm Fe}_{t} {\rm O}} $ as well as the slag oxidation ability of CaOFeO (s1), SiO2FeO (s2), CaOSiO2FeO (s3), CaOFeOAl2O3 (s4), SiO2MgOFeO (s5), SiO2FeOAl2O3 (s6), CaOSiO2FeOAl2O3 (s7), CaOSiO2MgOFeOAl2O3 (s8), SiO2FeOMnO (s9), SiO2FeOMnOAl2O3 (s10), FeOMnO (s11), FeOMnOAl2O3 (s12), CaOFeOCaF2 (s13), and CaOSiO2FeOCaF2 slags (s14) in a temperature range of 14731973K.; A thermodynamic model for calculating the mass action concentrations of structural units in CaOSiO2MgOFeOMnOAl2O3CaF2 slags, i.e., the IMCT-Ni model, has been developed based on the ion and molecule coexistence theory (IMCT).
