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, Fe<SUB>3</SUB>O<SUB>4</SUB> 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 S<SUB>2</SUB> for the liquid phase are derived.
