The thermodynamic behavior of Fe-Si liquid alloys is of considerable interest for understanding steelmaking processes and the role of silicon as a deoxidizer. In this study, the Chou model of solution thermodynamics is applied to evaluate the excess Gibbs free energy of mixing, activity, enthalpy of mixing and entropy of Fe-Si binary liquid alloys at 900 K. The model predictions are compared with available experimental and CALPHAD data, showing satisfactory agreement. The results provide a reliable basis for understanding alloying effects in Fe-Si melts.
