A coupled key phase diagram study and critical evaluation and optimization of all available experimental data of the Li2O-MgO-SiO2 system was performed to obtain a set of Gibbs energy functions to reproduce all the reliable phase equilibria and thermodynamic data. Differential scanning calorimetry ...

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 ...
A computer model of the T – x – y diagram of MgO–SiO 2 –Al 2 O 3 system is used to show the possibility of analysis of its microstructure constitution in terms of competition between primary and eutectic crystals by means of vertical mass balance diagrams calculated for a given centroi...
The phase diagram of the CaO–SiO2–ZrO2-7 mass% MgO system at 1873 K is initially calculated and shown in Fig. 1. It is noticed that the solubility of zirconia (ZrO2) in the liquid slag phase is relatively small, viz. about 2–3 mass% and the calcium zirconate (CaZrO3) phase is ...
通过运用FactSage中的Viscosity模块与PhaseDiagram模块进行计算,与实验测定的炉渣黏度进行对比。结果表明:在10%FeO-CaO-SiO2-MgO-15%Al2O3五元渣系中,MgO含量为12%时,炉渣黏度达到最低;在10%FeO-CaO-SiO2-10%MgO-Al2O3五元渣系中Al2O3的含量为12%时,炉渣黏度最低;当MgO/Al2O3在0.7~0.8之间,炉渣流动性...
