K-Ca-Mg-Cl-H2O体系中硫酸钙结晶介稳区的研究
Research into crystallization metastable zone property of calcium sulfate in K-Ca-Mg-Cl-H2O system
摘要
Abstract
The crystallization metastable zone of calcium sulfate in the system of K-Ca-Mg-Cl-H2O was investigated. The supersaturated solution of calcium sulfate was formed by reaction of calcium chloride solution and magnesium sulfate solution with certain concentrations, and the relationship between the supersaturation of calcium sulfate and its crystallization was studied in mixed salt solutions at different salt concentrations and different temperatures by the laser light scattering method. The corresponding solubilities of calcium sulfate were also determined in this system. Accordingly, the width of metastable zone of calcium sulfate crystallization was then determined. Further, the paper investigated the factors influencing the metastable zone, and also the inner connection among calcium sulfate crystallization and its phases with the factors of mixed salt solutions concentration,temperature and the crystallization metastable zone.关键词
