Calculation model of mass action concentrations for CaO–MgO–SiO2–Al2O3–Cr2O3 penta-slag

Two calculation models of mass action concentrations for CaO–MgO–SiO2–Al2O3–Cr2O3 penta-slag was presented whether 3CaO·Cr2O3·3SiO2 was existence or not. Equilibrium mass action concentration of each element structure was gained. And the models results were compared with experimental activity. The final results illustrated the model without 3CaO·Cr2O3·3SiO2 was suit for reality. The model could response the element structure of slag as well.
