Based on the fluidity model of Hildebrand, an explicit formulation has been proposed which allowsa priori predictions of solute diffusion coefficients in molten metals. However, only the size effects have been accounted for, and no consideration has been given to the interactions between the solute and the solvent. Despite these limitations the predicted values are in reasonable agreement with the experimental values of diffusion coefficients for a variety of solutes in a range of solvents over wide ranges of temperature. The equation suggested herein has no adjustable parameter.
