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 ...
The phase diagram of the TiO 2 -CaO-SiO 2 -10wtpct Al 2 O 3 -5wtpct MgO system in the TiO 2 -rich corner at 1773K has been established. The obtained phase diagram can provide reliable reference for the slag adjusting during vanadium-titanium magnetites smelting to make sure the ...
(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-TiO2slag 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 to...
