In the wet-process phosphoric acid production from the Hubei phosphate ore, one of the bothersome problems is that potassium fluosilicate and sodium fluosilicate scales are liable to form on the filtration system owing to its high potassium and sodium content, which greatly restrains the application of Hubei phosphate ore.

本文首先采用人工冷却系统模拟湿法磷酸生产的真空过滤系统冷却过程，研究垢物的析出规律，实验结果得知：垢物的主要成分为氟硅酸钠和氟硅酸钾，氟硅酸钠首先析出，结构致密，其次是氟硅酸钾，最后是二水硫酸钙，氟硅酸钠对氟硅酸钾有很强的结晶诱导作用；然后在三种生产中常用的不同的材质钼二钛、聚氯乙烯和聚四氟乙烯表面进行结垢试验，发现聚四氟乙烯表面最不易结垢，而在钼二钛表面最易结垢。

The mechanism of carbonization process of aluminate solution was analyzed thermodynamically. The results show that the internal reason of precipitation of Al3 in the process is its spontaneous nucleation caused by supersaturation of aluminate solution. The behaviors of SiO2 in the process are in accordance with that from published experiment, which implies that the content of product SiO2 from carbonization depends on its solubility but is not the result of absorption. The thermodynamic calculation for forming Na2O·Al2O3·2CO2· n H2O was achieved.

摘 要：为对高浓度铝酸钠溶液碳酸化分解过程中产品杂质含量的控制提供理论依据，分析了铝酸钠溶液碳酸化分解过程的热力学，认为该过程中Al3析出的真正机理是过饱和铝酸钠溶液的自发结晶；而基于分解过程中平衡浓度的热力学计算表明，在碳酸化分解过程中SiO2的变化规律与公认的三段变化规律一致，说明该过程产品中SiO2的含量取决于它在溶液中的平衡浓度，而非吸附所致；同时还分析了丝钠铝石的形成热力学。
