摘　　要：利用仿生合成原理,选取天冬氨酸作为诱导剂,采用沉淀反应法制备出糖果状球霰石型碳酸钙粒子,并对其结构和性能进行了表征.考察了反应温度、诱导剂用量和反应时间等对碳酸钙粒子晶型和形貌的影响,探讨了其反应原理.结果表明,所得碳酸钙粒子荧光性增强.此方法对碳酸钙的仿生合成与改性研究具有一定的指导意义.The aspartic acid(Asp)was used as the inducer and candy-like calcium carbonate particles were prepared by controlling the reaction conditions such as reaction time,the dosage of inducer,and the reaction temperature,and the optimum conditions for obtaining the candy-like calcium carbonate particles were obtained.The structure,morphology and properties of the resulting calcium carbonate particles were characterized and a reasonable reaction mechanism was proposed.The new ideas about the preparation of calcium carbonate with specific morphology will be instructive in related material researches.
