The viscosities of CaO-SiO2-Al2O3-MgO-FeO slags were measured under conditions of C/S=1.15-1.6, 10-13 mass% Al2O3, 5-10 mass% MgO and 0-20 mass% FeO. Slag viscosity decreased with increasing FeO content at a fixed basicity (CaO/SiO2) of slag. Slag viscosity at low FeO ( 1.3 would be increased with increasing the chemical potential of primary solid phase e.g. dicalcium silicate. A thermodynamic approach for the activity of primary solid phase in molten slags resulted in a reasonable relationship between viscosity and slag components. Therefore, it was confirmed that slag viscosity in basic slags (C/S>1.3) could be estimated by the chemical potential of dicalcium silicate.
