The viscosities of various FeO-SiO2 slags were calculated using a previously developed structural-based model. Using hole theory and the atomic pair model, an expression was derived to relate the viscosity to temperature and the fraction of the bridging oxygen in silicate melts. The deduced equation was successfully applied to predict the viscosities of FeO-SiO2 slags in the composition range of 0.1 < XSi02 < 0.423 for several temperatures. The calculated data agree well with the experimental viscosity data.
