Phase diagrams for the CaO-SiO2-FeOx system at various oxygen partial pressures are necessary for the design of raw material for ironmaking, the analysis of smelting reaction and ore sintering process. In this study, liquidus lines for the CaO-SiO2-FeOx systems at various oxygen partial pressures were observed at 1573 K by using chemical equilibration technique. The liquid phase area changed with changing oxygen partial pressure from 10−3 to 102 Pa (10−8 to 10−3 atm). The effect of Fe3+/Fe2+ ratio on the melting mechanism is discussed.
