In this work, the equilibrium distribution coefficients of phosphorus k^P0 in Fe-P binary and Fe-C-P ternary systems were obtained experimentally and the carbon content dependence of the equilibrium distribution of P was discussed using Distribution Interaction Coefficient. Temperature dependence of k^P, ^α_0 for α phase is given by k^P, ^α_0=N^s_P/N^l_P=0.715-3.2O×10^<-4>T. From the above equation, k^P, ^α_0 at infinite dilution of P, that is to say, at the melting point of iron, is 0.136, k^P, ^γ_0 for γ phase at high carbon concentration is about 0.09. k^P, ^γ_0 increases with the concentration of carbon and k^P, ^γ_0 at infinite dilution is 0.06. Also, the relation between k^X_0 of various elements for α phase and that for γ one was derived thermodynamically.
