N2 - Sulfur distribution ratios between CaO-Al2O3 slags and liquid iron were measured at 1873 K as a function of aluminum content using an alumina or a lime crucible. Activity coefficients of CaS relative to a solid standard state were obtained as 52±2.6 and 23±1.7 for the CaO-Al2O3 slags saturated with an Al2O3 and a CaO crucible, respectively, in the concentration range up to the CaS solubility limit. From these results, logarithm of the equilibrium constant, log KCaS, for the calcium desulfurization reaction CaS(s) = Ca+S and the first-order interaction parameter eS Ca (eS Ca) were estimated to be -8.72±0.27 and -269±28 (-336±35), respectively.
