The viscous behavior of the CaO–Al2O3–12 mass%Na2O–12 mass%CaF2 based slag system with various concentrations of Li2O has been studied using the rotating spindle method to understand the effects on the viscosity with these additives. Li2O additions up to 1 mass% significantly lowered the viscosity b...
