摘要

gamma_((P_2O_5)) was recalculated for a large number of slag compositions after incorporating appropriate interaction parameters for the solutes in liquid Fe. A correlation was developed for prediction of gamma_((P_2O_5)) from chemical composition and temperature of slag. The correlation was satisfactorily applicable to data of other workers as well. A Healy-type equation involving slag composition and temperature was developed, which made better prediction of phosphorus partition ratio than Healy's original correlation. No correlation of gamma_((P_2O_5)) with optical basicity of slag was observed.
