Calculation Model of Mass Action Concentrations for CaO-MnO-FeO-SiO₂-MgO-Al₂O₃ Slags Based on the Ion and Molecule Coexistence Theory

Abstract:

According to the ion and molecule coexistence theory (IMCT) of slag structure and corresponding phase diagrams, a thermodynamic model for calculating mass action concentrations of structural units or ion couples of CaO-MnO-FeO-SiO₂-MgO-Al₂O₃ slags was established. Equilibrium mass action concentrations of each structure unit were gained. And the calculation results of N_FeO and N_MnO were compared with measured a_FeO and a_MnO. The comparison shows that the calculated values of N_FeO and N_MnO are in good agreement with the reported measured values of a_FeO and a_MnO, so this calculating model could fairly describe the characteristics of the slag system.
