چکیده انگلیسی
The phase equilibria of the TiO2-CaO-SiO2-10wt.%Al2O3 system at the TiO2 rich corner were investigated experimentally by the quenching method with subsequent electron probe microanalysis. The investigations were carried out at 1773Â K and 1873K. The isothermal section at 1773Â K contains one liquidus region and two solid-liquid coexistence regions, liquid-CaTiO3 and liquid-TiO2. And the isotherms of the CaTiO3 primary phase field and TiO2 primary phase field at 1773Â K have been found in the TiO2 rich part. At 1873K, the CaTiO3 primary phase field and its isotherm have been determined. Based on the obtained fundamental data, the phase diagram has been established in the TiO2 rich corner of the TiO2-CaO-SiO2-10wt.%Al2O3 system at 1773Â K and 1873Â K. From the obtained phase diagram, it can be found that the addition of 10% Al2O3 into TiO2-CaO-SiO2 system enlarges the range of the low-liquidus-temperature slags. The phase equilibria data can provide the foundation for the further full investigations on the crystallization and upgradation of the Ti-bearing slag from direct reduction-smelting processes of vanadium-titanium magnetites.
