| 摘 要： | 用L-苯丙氨酸为模板,氯化钙和碳酸钠反应而制备碳酸钙纳米晶体,采用红外光谱和粉末X-射线衍射方法对其进行表征,通过扫描电镜观察纳米晶体的形貌,研究反应温度和L-苯丙氨酸浓度对碳酸钙纳米晶体的晶型和形貌的影响。研究表明:随着温度和L-苯丙氨酸浓度的升高,高能量晶型的含量增加,说明升温和增加L-苯丙氨酸浓度能够促进稳定碳酸钙晶型的生长。

| Abstract: | Reaction of calcium chloride and sodium carbonate by using of L-phenylalanine as a template resulted in growth of calcium carbonate nano-crystal which was characterized by the infrared spectroscopy and powder X-ray diffraction(XRD),and the shapes of calcium carbonate nano-crystals were further observed by scanning electron microscope(SEM).Influence of L-phenylalanine concentration and reaction temperature to polymorphs and shapes of calcium carbonate nano-crystals was also investigated,which indicated that ... |
