In the present study, the sulfide capacities of the slags in the ternary Al 2 O 3 –CaO–SiO 2 system at 1873 K, and in the quaternary system Al 2 O 3 –CaO–MgO–SiO 2 at 1823 and 1873 K are experimentally measured using copper–slag equilibrium at controlled oxygen partial pressure. The experimental data, which has been unavailable, are needed for the improvement of a sulfide capacity model. An assessment of the available data for sulfide capacities in the Al 2 O 3 –CaO–MgO–SiO 2 system and its sub lower‐order systems are made. Based on this assessment and the present experimental results, the model parameters of the existing sulfide capacity model are re‐optimized. The sulfide capacity model can be successfully used in the prediction of the sulfide capacities of multicomponent slags with satisfactory accuracy.
