Abstract Recent proposal of utilisation of impurities in steel requires preservation of phosphorus in molten steel during its refining process. To know the phosphorus absorbing ability of deoxidation by-product slag having CaO, the phosphorus partition has been investigated between the MnO-SiO2-FetO-CaOMgO- P2O5 slag and molten iron in this study. The phosphate capacities (CPO4 3-) for the present slag has been determined as a function of temperature and optical basicity has follows; logCPO4 3- = (11 300Λ + 54 560)/T + 18.30Λ －27.43 CaO was found useful to improve phosphate capacity of this system to some extent.
