摘要
以碱土金属锶的硝酸盐为添加剂,采用"一步法"制备了大小均一、分散性良好的花椰菜状碳酸钙粒子.考察了反应温度、反应时间等因素对碳酸钙结晶行为的影响,确定了最佳反应条件.利用扫描电子显微镜(SEM)、X射线衍射仪(XRD)、X射线能谱仪(EDAX)等对所得产物的结构和性能进行了表征,并探讨了其反应原理.
Strontium nitrate as an additive was added in the system to prepare uniform distributed broccoli-like calcium carbonate particles. The one-step synthetic method was used which is safe and environment-friendly. The resulting calcium carbonate was characterized through scanning electron microscope( SEM),X-ray diffraction( XRD) and energy dispersive X-ray analysis( EDAX). Meanwile,the possible reaction mechanism of calcium carbonate was put forward.
