Results of a study of phase equilibria in the system CaO–TiO 2 –SiO 2 are presented. A prominent feature of the liquidus surface is a large two-liquid region which appears on the equilibrium diagram as a broad band extending from the SiO 2 -CaO side to the SiO 2 -TiO 2 side of ...
(EDX) analysis.The liquid phase(L),melilite solid solution phase((C2MS2,C2AS)ss),diopside phase(CMS2) and perovskite phase(CaOTiO2) are found.Coupled with the liquidus lines and equilibria results,the phase diagram is constructed for the specified region of the CaO-SiO2-5%MgO-20%...
The phase diagram of the CaO-SiO2-Nb2O5-Fe2O3-TiO2 slag system has important significance for guiding the recycling and utilization processes of metallurgical slags containing niobium and titanium. In this paper, high-temperature equilibrium experiments were conducted at 1100 掳C in air atmosphere...

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 1773 K and 1873 K. From the obtained phase diagram, it can be found that the addition of 10% Al2O3 into TiO2-CaO-SiO2 system enlarges...
Phase diagramRecoveryIn the Selective Crystallization and Phase Separation (SCPS) process, manganese oxide is used as an additive to promote the precipitation of perovskite. However, the influence of manganese oxide on the liquid domain of the perovskite primary phase field is still unclear. In the...
In the present work, the phase equilibrium relationships were investigated for the CaO-SiO2-5wt%MgO-10wt%Al2O3-TiO2 phase diagram system. The equilibrium phases were experimentally determined at 1300 °C and 1400 °C using the high temperature equilibrium technique followed by X-Ray Fluoroscopy ...
