水合盐形成条件的化学键参数分析

Chemical Bond-Parametric Analysis of Formation Regularities of Salt Hydrates

根据240种无机盐的水合盐形成与否的实验数据,应用化学键参数 模式识别方法总结水合盐的形成规律,得到了几种价型的无机盐水合物的形成判据.并用类似算法研究了氯化物、溴化物水合复盐形成以及水合盐结构参数z/xn的若干规律性.这些规律对水合盐材料和水盐系相图的计算机预报有参考价值.

A chemical bond-parametric method has been used to find regularities in the formation of (hydrated) salts by analyzing the hydrate formability data of 240 inorganic salts. Some criteria of hydrate formation of the inorganic salts of several valence-types have been obtained. Besides, the regularities of formation of hydrated double chlorides or bromides and the regularity of the lattice structure parameter z/xn of hydrated salts are also investigated. These regularities are useful for the computerized prediction of hydrated salt materials and the phase diagrams of salt-water systems.
