摘要
测试了超声波和氢氧化钙悬浮液波美度对碳化法制备的碳酸钙粒径的影响。结果表明 ,超声波可使碳酸钙的粒径由 10 0nm左右减小到 2 0nm左右 ,且粒径更均匀 ,晶形更规则 ,分散性更好 ;并且氢氧化钙悬浮液波美度越低 ,所得碳酸钙的粒径越小。
The effects of ultrasonic and Baumé degree of calcium hydroxide suspension on the size of CaCO 3 prepared by carbonization were tested. The results indicate that ultrasonic can reduce the size of CaCO 3 from about 100nm to about 20 nm and make the size more even, the shape of crystals more regular and the dispersivity better, moreover, the lower Baumé degree of calcium hydroxide suspension, the smaller the size of CaCO 3.
