    Effects of additives (Li2O, Na2O, K2O, MgO, BaO, Al2O3, Fe2O3, TiO2, NaF, CaF2) on viscosities of CaO-SiO2 (CaO/SiO2 = 1) melts have been studied by a crucible-rotating method. Viscosities of CaO-Al2O3-Fe2O3 melts also have been measured. The addition of Al2O3 lead to increase the viscosities of CaO-SiO2 (CaO/SiO2 = 1) melts, and the viscosities of CaO-SiO2 (CaO/SiO2 = 1) melts decreased with the addition of the other elements. The viscosities of CaO-Al2O3-Fe2O3 melts of constant CaO content decreased with the substitution of Fe2O3 for Al2O3. Iida's equation for viscosity reproduced the experimental viscosity data for CaO-SiO2 (CaO/SiO2 = 1) melts except for high Al2O3 content (40 mass% Al2O3) slag.
