Formatted abstract
The Fe–O system has been assessed over the whole composition range to produce a self-consistent set of thermodynamic properties of all condensed phases from 25 °C to above the liquidus temperatures at ambient pressure. The liquid phase from metallic liquid to oxide melt is described by a single model developed within the framework of the Quasichemical Formalism. The model reflects the existence of strong short-range ordering in oxide liquid at approximately FeO and Fe2O3 compositions. Parameters of thermodynamic models have been optimized to reproduce all available thermodynamic and phase equilibrium data. In particular, the heat capacity and entropy of wüstite is described better than in the previous assessments.
