A theoretical equation for the interaction parameters in multi-component metallic solutions has been recently presented by the pseudopotential formalism for the free energy with the free energy of the hard sphere model. By applying this new theoretical equation, numerical calculations were made on 280 cases in iron-base solutions closely related to steelmaking and the agreement between calculation and the available experimental data appears to be at the reasonable level with 90% reliability of agreement in sign. It was also appreciated for the hard sphere term that the product of the difference in the hard sphere diameters between solvent and solute plays a significant role in determining the sign and absolute values of the interaction parameters.
