In this study, the foaming index of CaO-SiO{sub 2}-Fe{sub t}O and CaO-SiO{sub 2}-Fe{sub t}O-Al{sub 2}O{sub 3} slags saturated with MgO was measured to understand the relationship between their foaming behavior and physical properties. The foaming index of MgO-saturated slags increases with the Fe{sub t}O content due to the redox equilibrium of Fe{sub t}O. Experimental results indicated that MgO-saturated slag has relatively high ferric ion concentration, and the foaming index increases due to the effect of ferric ion. Therefore, the foaming behavior of MgO-saturated slag is more reasonably explained by considering the effect of ferric ion on the estimation of slag properties such as viscosity, surface tension, and density. Specifically, the estimation of slag viscosity was additionally verified by NBO/T, and this is experimentally obtained through Raman spectroscopy.
