| 摘 要： | 氯化镁是碳化法合成碳酸钙晶须的有效控制剂。通过研究氯化镁溶液的回收利用,结果表明:随着回收次数的增加,碳酸钙晶须的纯度和尺寸都逐渐降低;适当降低反应溶液的初始镁钙比,可以提高碳酸钙晶须的长径比。当镁钙比为1.7时,可以制得长度27.7μm,长径比为26的碳酸钙晶须。

| Abstract: | Calcium carbonate whiskers were synthesized by carbonation method using magnesium chloride as a reaction controller.The paper studied the problem of the recycling and using of magnesium chloride solution.The results indicate that the purity and size of calcium carbonate whiskers are gradually reducing with increasing the times of recycling.Properly reducing the ratio of magnesium and calcium in the initial reaction solution can improve the aspect ratio of calcium carbonate whiskers.When magnesium to calcium... |
