Nitrogen and sulfur distribution ratios between CaO-Al_2O_3 slag and Fe-0.0001∿33 mass% Al alloys were measured in the temperature range of 1823 to 1923K, using Al_2O_3 and CaO crucibles. The distribution ratios under a CaO crucible were higher than those under an Al_2O_3 crucible, and increased with an increase of Al content. Nitride and sulfide capacities defined by C_<N^<3->>=(mass%N)・P_<O_2>^<3/4>/P_<N_2>^<1/2> and C_<S^<2->>=(mass%S)・P_<O_2>^<1/2>/P_<S_2>^<1/2>, respectively, which were obtained by using the reported values for activity of Al_2O_3, agreed well those directly measured in a gas-slag experiment under an Al_2O_3 curcible, but disagreed with those under a CaO crucible. Activities of Al_2O_3 in the CaO-Al_2O_3 melts saturated with CaO were evaluated based on the results in the gas-slag experiments.
