摘要：
Activities of the oxide components in the 'FeO'-MgO-SiO2 and 'FeO'-MnO-SiO2 systems have been predicted based on the information of binary systems using a thermodynamic model. The model considers the ionic melt as an oxygen-ion matrix with the cations including Si4+ distributed in it. The interactions between different cations in the presence of O2- are considered as functions of both composition and temperature. The activities predicted by the model are in good agreement with the experimental data available in the literature.
