Experiments of dephosphorization of the molten iron containing manganese (13-35 wt%), carbon (0-5wt%), and phosphorus (0.1 wt%) by the Na_2O-based fluxes (Na_4SiO_4, Na_4SiO_4-NaF) were carried out in a temperature range from 1300℃ to 1550℃. The effects of carbon and manganese contents in the molten iron, NaF and MnO_2 additions to the flux, and temperature on dephosphorization were investigated. Phosphorus distribution ratios obtained at the end of runs as affected by carbon content in the melt and Na_2O and MnO contents in the slag were also investigated. In addition, the equilibrium concentration of phosphorus in molten iron was calculated from the thermodynamic data. The calculated phosphorus concentration was represented in terms of manganese and carbon contents in molten iron and compared with the observed one.
