with the mantle transition zone, the MAS phase diagram markedly simplifies, with the three pure oxides (i.e. MgO, periclase; Al2O3, corundum; SiO2, stishovite) displaying a primary phase field and majorite-pyrope garnet as the only, and most important, ternary liquidus phase in the ...

This study utilized the single hot thermocouple technique to examine the dissolution behavior of lumped magnesium oxide (MgO) in CaO–Al2O3–SiO2 ternary slags. The aluminum oxide (Al2O3) content in the slag (C/S = 1) varied from 10% to 30%; the MgO sphere with a diameter of 1 mm...
Phase Equilibria in High‐Alumina Part of the System CaO–MgO–Al2O3–SiO2 Results are presented of a study of phase equilibria among crystalline and liquid phases in the quaternary system CaO–MgO-Al 2 O 3 –SiO 2 at Al 2 O 3 c... R.C. De Vries,E.F. Osborn - 《Journal of ...
Phase equilibria of the CaO-SiO2-TiO2-Al2O3-MgO system in air at 1250-1400 degrees C The equilibrium phase relations of the CaO-SiO2-TiO2-Al2O3-MgO system were investigated experimentally in air at 1250-1400 degrees C using a high-temperatu... M Chen,J Shi,P Taskinen,... - 《Cera...
support these findings64shows that temperature of 750 °C provide high IG/ID. However, some defects also present in CNTs structure. Pawar et al.65proposed that higher temperature could lead to higher carbon nano-structure deposit on Ni/γAl2O3catalyst along with increase CH4/CO2ratio in ...
A complete literature review, critical evaluation, and thermodynamic modeling of the phase diagrams and thermodynamic properties of all oxide phases in the MgO-Al2O3, CaO-MgO-Al2O3, and MgO-Al2O3-SiO2systems at 1 bar total pressure are presented. Optimized model equations for the thermodynamic...
CaO–SiO2–Al2O3–MgO is a basic system of ironmaking slag in which CaO and MgO are mainly come from the flux, SiO2 and Al2O3 are mainly from the raw materials. Effect of raw material composition on phase equilibrium of the slag can be described by a pseudo-ternary system (CaO?+?
In this study, new experimental phase diagram data were also collected and a critical evaluation and optimization of the thermodynamic properties and phase diagrams of the CaO-MgO-AlO-SiO-ZrOsystem was performed. As an example, the optimized ZrO-SiObinary system and ZrO-CaO-MgO ternary system ...
The liquid phase boundaries in the CaO-Al2O3-MgO, CaO-Al2O3-ZrO2, CaO-SiO2-TiO2, CaO-SiO2-MgO and CaO-SiO2-Al2O3 ternary slags were determined at 1 873 K by using a slag-crucible (CaO, MgO, Al2O3 and ZrO2-11mol%CaO) equilibration technique. The equilibrium phase at crucible-...
