摘要
采用鼓泡碳化法 ,在最佳反应温度、反应物浓度的条件下 ,考察了添加剂对产物形状及粒径大小的影响 ,得到了直径为 2 0～ 30nm、长径比在 2 0左右且分散性能良好的针状纳米碳酸钙 ,并对添加剂作用机理进行了分析。
The additive is used to control the size and the shape of CaCO 3?Needle like nanometer CaCO 3 with the diameter of 20～30 nm and the aspect ratio of 20 are synthesized by introducing CO 2 to lime suspension under the optimum condition.The products are imparted high dispersibility.The mechanism of additive is studied.
