Thermodynamic Evaluation of Interaction Parameters of Solutes in Molten Iron
Year: 2025
Type: article
Abstract: The concentration dependence of the activity coefficients of solutes in molten iron is expressed in terms of interaction parameters. The interaction parameters were determined by the experiments under thermodynamic equilibrium and the evaluation had been based only on the accuracy of the experiments. An evaluation of the interaction parameters is proposed due to the thermodynamic stability of homogeneous solution, and is applied to several interaction parameters of the solutes of O, S, Ca and Al in molten iron at 1600°C.
