Phase equilibria in Fe–Mn–S and Fe–Cr–S ternary systems at 1843 K were investigated experimentally, respectively. The main characteristic of these two systems at 1843 K was confirmed to be a wide miscibility gap between two liquid phases: molten metal alloy phase and molten sulfide phase. Through metal/sulfide equilibrium method, activity of constituents in sulfide phase were determined in Fe–Mn–S and Fe–Cr–S systems separately. The activity curves of constituents in sulfide phase were estimated by utilizing regular solution model.
