摘要：

In the present study, the viscosity experimental data for the FetO-containing silicate melts under oxidation atmosphere, which Fe3+ and Fe2+ co-exist were critically evaluated and model parameters related to Fe2O3 were optimized to best reproduce all reliable experimental viscosity data. The charge compensation effect on the viscosity for the systems containing Fe2O3 was modeled with the Gibbs energies for LiFe, NaFe, KFe and CaFe2 "associate species" formation. The viscosities of a wide compositional and temperature range of binary, ternary and multicomponent melts containing Fe2O3-FeO-SiO2-Al2O3-CaO-MgO-Li2O-Na2O-K2O-MnO-Ti2O3-TiO2 were well reproduced by the present model within the scatter of experimental data.
