Abstract

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.
