Phase equilibrium and oxygen partial pressure for the Fe-S-O system from eutectic temperature to 1673 K were investigated by chemical equilibrium techniques and the EMF method. The liquid phase is saturated with Fe, FeO, Fe3O4 and FeS. The partial pressure of oxygen increases remarkably with departing from the liquidus saturated with Fe. According to the Gibbs-Duhem equation and Schumann's method, the activities of Fe and the partial pressure of S2 for the liquid phase are derived.
