Abstract	Ti-bearing CaO-SiO$_{2}$-MgO-Al$_{2}$O$_{3}$-TiO$_{2}$ slags are important for the smelting of vanadium-titanium bearing magnetite. In the current study, the pseudo-melting temperatures were determined by the single-hot thermocouple technique for the specified content of 5 to 25 pct TiO$_{2}$ in the CaO-SiO$_{2}$-5 pctMgO-10 pctAl$_{2}$O$_{3}$-TiO$_{2}$ phase diagram system. The 1573 K to 1773 K (1300 °C to 1500 °C) liquidus lines were first calculated based on the pseudo-melting temperatures according to thermodynamic equations in the specific primary crystal field. The phase equilibria at 1573 K (1300 °C) were determined experimentally using the high-temperature equilibrium and quench method followed by X-ray fluorescence, X-ray diffraction, scanning electron microscope, and energy dispersive X-ray spectroscope analysis; the liquid phase, melilite solid solution phase (C$_{2}$MS$_{2}$,C$_{2}$AS)$_{ss}$, and perovskite phase of CaO·TiO$_{2}$ were found. Therefore, the phase diagram was constructed for the specified region of the CaO-SiO$_{2}$-5 pctMgO-10 pctAl$_{2}$O$_{3}$-TiO$_{2}$ system.
