Phase diagrams for the CaO-SiO 2 -FeO x 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-SiO 2 -FeO x systems at various oxygen partial pressures were observed at 1 573 K by using chemical equilibration technique. The liquid phase area changed with changing oxygen partial pressure from 10 - 3 to 10 2 Pa (10 - 8 to 10 - 3 atm). The effect of Fe 3 + /Fe 2 + ratio on the melting mechanism is discussed. |
