摘要: 以MgCl2·6H2O与NH4 HCO3为反应原料,采用低温液相法合成了棒状三水碳酸镁晶体,采用XRD,SEM对制备试样进行了测试表征,确定了棒状三水碳酸镁晶体的制备条件.在此基础上,分别采用Avrami方程和Nielsen方程,初步建立了棒状三水碳酸镁晶体的动力学模型

关键词: 三水碳酸镁;合成;结晶动力学

Abstract: MgCl2 ·6H2O and NH4 HCO3 were adopted as the raw material,the bar shaped nesquehonite crystals were synthesized with low temperature liquid phase method. And the samples prepared were characterized by XRD,SEM to determine the preparation conditions of bar shaped nesquehonite crystal. On this basis,the dynamic model of rod like magnesium carbonate crystals was established by using Avrami equation and Nielsen equation.

Key words: nequehonite;synthesis;crystallization kinetics
