A critical assessment of thermodynamic and phase diagram data for the CaO-SiO 2 system has been carried out using an extended Kapoor—Frohberg cellular model for the liquid phase. The assessment incorporates re
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...
Therefore, the phase equilibria and phase diagram of the FetO-TiO2-CaO-SiO2 system is essential to understand the recrystallizing behavior of the Fe2O3 modified titanium-bearing blast furnace slag. In addition, the weight ratio of CaO to SiO2 of the titanium-bearing blast furnace slag is ...

phase equilibria of CaO-SiO2-La2O3-Nb2O5system were determined. Finally, the 1200 °C isothermal phase diagram of CaO-SiO2-La2O3-Nb2O5system in reducing atmosphere was constructed, in which the L+CN+CS+S, L+CN+CS+LN, L+CS+S, L+CN+LN, L+CN+CS, L+CN+S equilibrium phase ...
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...
