Twelve kinds of phase equilibria were determined, and then a spatial liquidus phase diagram was constructed. The primary phase fields of SiO 2 , CaNb 2 O 6 , LaNbO 4 , Ca 2 Nb 2 O 7 and CaSi 3 La 4 O 13 were determined, respectively. Meanwhile, the liquidus surfaces in the ...
相(phase)是指体系内部物理性质和化学性质完全均匀的部分。相图(phase diagram)是用图的形式表明一个相平衡体系的组成、温度、压力和状态之间的 关系。相图可明确地反映所研究的体系中任一组分在各温度、压力下所存在的 相态、相成分和各个相的含量以及当温度、压力变化时相变类型及转变温度。
首先打开FactSage软件的Phase Diagram相图计算模块,在Components栏下输入第一个组分CaO后,再点击+依次输入另外两个组分Al2O3和SiO2。 打开Units窗口选择合适的单位,这里温度选择℃,质量选择g为单位。对于CaO-Al2O3-SiO2体系,Data Search窗口中选择氧化物数据库[FToxid]。然后点击Next进入下一步。 选择计算中可能涉及...

其操作界面如图 1.17,主要由数据库、计算及处理等三大模块构成,其中数据 库模块包括 Documentation、View Data、Compound 和 Solution;计算模块包括 Reaction、 Predom、EpH、Equilib、Phase Diagram 与 OptiSage;处理模块包括 Results、Mixture、Fact-XML、 Figure 以及 Viscosity,其中 Viscosity 是该版本的新增内容,用于...
Comparisons between the newly constructed diagram, existing data and FactSage predicted phase diagrams were performed and differences discussed. The present study will be useful for guidance of industrial practices and further development of thermodynamic modelling.doi:10.1111/jace.17421...
During firing the conductive phase based on CaRuO3 in lead-free thick-film resistors decomposes, presumably due to interactions with the silica-rich glass phase. Subsolidus equilibria in the CaO-poor part of the RuO2–CaO–SiO2 diagram were studied with the aim of investigating possible interacti...
