Phase diagrams for the CaO-SiO2-FeOx-Al2O3 or -MgO systems at various oxygen partial pressures are necessary for the design of raw material for ironmaking, the analysis of smelting reaction and sintering process. To clarify the effect of Al2O3 or MgO content on the formation of melts in the sintering process is important for the development of new sinter. In this study, liquidus for the CaO-SiO2-FeOx-Al2O3 or -MgO systems at various oxygen partial pressures were observed at 1 573 K by using chemical equilibration technique. The liquid phase area changed with adding Al2O3 or MgO. The effect of the Fe3+/Fe2+ ratio on the melting mechanism is discussed.
