摘要
以实测相图为依据选择溶液的基本相,采用FACT软件计算了复杂的Al2O3-CaO-SiO2三元氧化物体系的两个等温截面和两个多温截面,并根据实测相图绘制了同等条件下的截面图,对其进行验证分析。结果表明,由于Al2O3-CaO-SiO2三元系化合物数量多,结构复杂,计算相图与实测相图相差较大。在用FACT软件计算组元间相互作用较强的氧化物体系相图时,尚需进一步改进计算模型,完善热力学数据库。存在强相互作用的三元氧化物体系的等温截面和多温截面应以实验数据为基础,同时参考计算相图。
The basic phase is selected according to the measured phase diagram, two isothermal sections and two vertical sections of the Al 2O 3-CaO-SiO 2 ternary system are calculated using FACT software. The sections in the same conditions are described through the measured phase diagram. Because of the complexity of this ternary system, there is a large difference between the measured and the calculated phase diagram. It is necessary for FACT to ameliorate the calculation model and perfect the database in calculating oxide system which the interaction is strong. For this kind system, the isothermal section and vertical section should be founded through the experiment result and referencing the calculated phase diagram at the same time.
