Phase equilibria in the MgO-SiO2-TiOxsystem at 1873 K were investigated under controlled atmosphere by employing the method of high-temperature equilibration followed by quenching, electron probe microanalysis (EPMA) and XRD analysis. Based on the experimental results, isothermal phase diagram of the MgO-SiO2-TiOxsystem under oxygen partial pressure of 4.85 × 10−11atm was constructed. By comparing with the phase diagram of MgO-SiO2-TiO2, the effect of oxygen partial pressure on the phase relations was obtained. Firstly, anosovite (Ti3-xMgxO5) replaces TiO2and MgTi2O5to equilibrate with liquid phase. Secondly, the compound MgTiO3no longer exists under the reducing condition. Thirdly, the single liquid region shrinks due to the lower oxygen partial pressure. Furthermore, the equilibria between liquid and anosovite were investigated under other two oxygen partial pressures of 1.94 × 10−9and 2.75 × 10−13atm, respectively. The saturated solubility of titanium oxide in the liquid phase decreases with the decreasing of the oxygen partial pressure and higher SiO2content increases the activity coefficient of TiOxin liquid phase.
