- Abstract
Phase equilibria for the CaO–MgO–SiO2–13 wt pct Al2O3–50 wt pct TiO2 system were experimentally investigated at 1400 °C in air atmosphere, employing the high-temperature equilibration and quenching method. Seven distinct phases were identified, encompassing a liquid phase, a liquid phase with perovskite (CaTiO3), a liquid phase with rutile (TiO2), a liquid phase with anosovite (M3O5), a liquid phase with anosovite and rutile, a liquid phase with anosovite and spinel, and a liquid phase with perovskite and spinel. Additionally, an experimentally verified isotherm at 1400 °C was obtained and conducted a comparative analysis with predictions generated using FactSage software. Overall, the FactSage 8.1 software exhibited a notable tendency to overestimated the liquidus temperatures in the M3O5 and spinel phases regions when compared to the experimentally determined values. This disparity may be attributed to limitations in the FactSage 8.1 software database which lack of Al2TiO5 in the "FToxid-PSEU" solution species, as it indicated a large liquid phase region in the CaO–MgO–SiO2–13 wt pct Al2O3–50 wt pct TiO2 system at 1400 °C than what we experimentally determined.
