采用ＮＨ４ＨＣＯ３溶液逐滴加入浓的ＭｇＣｌ２水溶液中，经回流沸腾制得氯碳酸镁盐的晶体２ＭｇＣＯ３·Ｍｇ（ＯＨ）２·ＭｇＣｌ２·６Ｈ２Ｏ．该复盐在水中的溶解分为三个阶段：可溶解的ＭｇＣｌ２被溶脱阶段，诱导阶段及转化阶段．发现最终产物为４ＭｇＣＯ３·Ｍｇ（ＯＨ）２·ｍＨ２Ｏ，ｍ值与温度有关．采用不同的动力学模型进行处理．发现该复盐的溶解过程符合Ｓｔｕｍｍ方程，受控于扩散．还计算了转化生成的不同结晶水碱式碳酸镁盐的结晶动力学方程．由实验结果证实了水菱镁矿是由氯碳酸镁盐转化形成的．
NH4HCO3 solution was added dropwise to a concentrated aqueous MgCl2 solution to obtain a solution of magnesium chlorocarbonate 2MgCO3 · Mg (OH) 2 · MgCl2 · 6H2O by reflux boiling. The complex salt dissolved in water is divided into three phases: soluble MgCl2 is stripped stage, induction stage and transformation stage. The final product was found to be 4 MgCO3 · Mg (OH) 2 · mH2O and the value of m was related to temperature. Different kinetic models were used for processing. The complex salt was found to be in accordance with the Stumm equation and controlled by diffusion. Crystallization kinetics equations of different crystalline water-borne magnesium carbonate salts were also calculated. From the experimental results confirmed that hydromagnesite is formed by conversion of chlorocarbonate.
