Abstract
A model to estimate the viscosity of aluminosilicate melts including alkali oxides, as derived in our previous study, was extended to molten slag systems containing CaF2. The bonding state of oxygen in molten silicate and the flow mechanism of melts with a network microstructure were considered for this model. To evaluate the bonding states of oxygen for given chemical compositions, a model proposed by Susa et al. was applied. Their model is easily extended to any multi-component molten slag system without the need to consider thermodynamic parameters. In this work, the above-mentioned viscosity model was applied to evaluate the effect of CaF_2 on the viscosity of molten SiO_2–CaO–CaF_2, SiO_2–CaO–Al_2O_3–CaF_2 and SiO_2–Al_2O_3–CaO–CaF_2–Na_2O–MgO systems.
