摘　　要：首先采用化学分析法测定制盐母液中各个离子的浓度,通过单因素实验来确定制备碱式碳酸镁的适宜反应温度。在确定的实验条件下制备出碱式碳酸镁,用XRD分析碱式碳酸镁的晶体结构、以SEM图分析其表面形貌。进一步实验可制备出氧化镁晶须,以SEM分析其结构和形貌。Firstly, the concentration of each ion in the mother liquor of salt production was determined by chemical analysis. The optimum reaction temperature for preparing basic magnesium carbonate was determined by single factor experiment. Basic magnesium carbonate was prepared under certain experimental conditions. The crystal structure of basic magnesium carbonate was analyzed by XRD, and its surface morphology was analyzed by SEM diagram. The Magnesium Oxide whiskers can be prepared by further experiments and their structures and morphologies are. analyzed by SEM.
