Phase equilibria along the nonbinary join between cordierite (2MgO · 2Al 2 O 3 · 5SiO 2 ) and spodumene (Li 2 O · Al 2 O 3 · 4SiO 2 ) were investigated in the temperature range 800° to 1550°C. using the quench technique on fourteen compositions. The phase diagram at high...
According Li2O-Al2O3-SiO2(LAS) system glass phase diagram,a set of compositions were designed. 实验以Li2O-Al2O3-SiO2(LAS)系统微晶玻璃为研究对象,根据LAS系统玻璃三元相图设计玻璃组成,并在基础组分不变的前提下,选择了La2O3等5种稀土氧化物采取外加法进行掺杂,应用高温粘度仪测试分析了玻璃液的高温粘度...
A coupled phase diagram experimental study and thermodynamic optimization of the Li2O-CaO-Al2O3 and Li2O-CaO-SiO2 systems, and prediction of the phase diagrams of the Li2O-CaO-Al2O3-SiO2 system - ScienceDirectLi2O-CaO-Al2O3Li2O-CaO-SiO2...
In spite of their interest, the thermodynamic properties and phase diagrams of PO-bearing systems are still not well known yet. As a result, we critically reviewed and optimized the structural, thermodynamic and phase diagram data belonging to the system LiO-NaO-CaO-FeO-FeO-AlO-SiO-PO. This ...
