Phase Equilibrium studies in the system “FeO”–SiO2–Al2O3–CaO–MgO at 1200 °C and Po2 108atm

Phase Equilibrium Studies of Nonferrous Smelting Slags: A Review

“…Henao et al [42] reported the phase equilibria of the "FeO"-SiO 2 -CaO-MgO-Al 2 O 3 system at Po 2 = 10 −8 atm and 1250 to 1350 • C. This study focused on the tridymite primary phase field at a fixed amount of 3.3 wt% of Al 2 O 3 or 3.3 + 3.3 wt% of MgO + Al 2 O 3 . Xie et al [43] studied 1200 • C isotherms of the "FeO"-SiO 2 -CaO-MgO-Al 2 O 3 system at a fixed Po 2 of 10 −8 atm. Effects of up to 6 wt% of MgO and/or Al 2 O 3 on the isotherm positions were discussed.…”
