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...
The diagram for FMBeAS shows that sapphirine + quartz, which is often cited as evidence for ultrahigh temperatures (e.g., ≥ 1040 °C), is stabilized to lower T and higher P than in the corresponding Be-free system. Hence, this minimum T may be valid only in rocks with relatively abu...
The subsolidus structure of the phase diagram of the MgO - Al2O3 -SiO2 system is studied and the boundaries of the domains of existence and the probability of the existence of all stable phases in the entire temperature region are determined. The temperature of the pseudobinary spinel — ...

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 ...
