Compact Al2O3-MgO·Al2O3-CaO·6Al2O3 (AMC) composite was obtained by melting technology using industrial alumina, light-burned magnesia, and quick lime as raw materials based on the Al2O3-MgO-CaO ternary phase diagram. The results show that the phases of MgO·Al2O3 and Al2O3 are...
Phase diagramHigh pressure•Melting phase relations in the MAS system are predicted through an integrated theoretical and computational approach.•Liquidus topology of binary and ternary phase diagrams is computed up to very HP-HT conditions (i.e. 25GPa and 5000K).•Pressure effects produce a...

The effect of different oxides in vanadium slag, such as MgO, MnO, and Al2O3on vanadium extraction in the sodium roasting-water leaching process has been investigated. The results show that the increase of these oxides has a positive influence on the conversion rate of vanadium. At the condi...
Phase stability diagram of spinel formation in liquid steel was assessed as a function of aluminum, magnesium and oxygen contents in iron at 1 873 K. The predicted phase boundaries of MgO·Al2O3, MgO and Al2O3 agreed well with previous observations by one of the present authors. 展开 ...

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 ...
phase diagram) is sensitive to changes in both temperature and pressure, whereas the governing diffusivity depends only on temperature. Introduction The technological importance of MgO (periclase) and Al2O3 (corundum) in refractory ceramics has prompted numerous studies of the kinetics of the reaction...
Figure 1. Presentation of the pseudo-ternary phase diagram in the CaO-MgO-(SiO2+Al2O3) system at fixed Al2O3/SiO2 weight ratio of 0.4. The microstructures and phase compositions of the quenched samples were determined by EPMA. Anorthite (CaO·Al2O3·2SiO2), cordierite (2MgO·2Al2O3...
The dissolution behavior and the formation of MgAl2O4 were analyzed by a phase diagram provided by Factsage 7.0 software. In the case of less than 20% Al2O3 content, apparent sphere radii were measured; the shrinking core model was then applied to understand the dissolution mechanism. The ...
