"A study of phase relations and thermodynamic properties of phases in the system CaO-FeO-Fe₂O₃-SiO₂ was conducted at 1450°C and 1550°C. The region of stability of the different phases was determined by microscopic examination of the specimens. The thermodynamic properties of liquid were determined by analyses of quenched samples equilibrated at oxygen pressures from about 10⁻¹¹ to 1 atm. Isothermal phase diagrams were constructed from data for 0, 5, 10, 20, and 30 weight percent silica sections of the CaO-FeO-Fe₂O₃-SiO₂ system, and the effect of temperature and increased silica additions on the oxygen solubility of the liquid oxides was measured. Multicomponent Gibbs-Duhem integrations were used to calculate the activities of the oxide components CaO, FeO, and SiO₂ from the measured oxygen activity data on the liquid oxides. The results were discussed in terms of the formation and behavior of slags in the Basic Oxygen Furnace steelmaking process"--Abstract, page [ii].
