摘要
Abstract
Calcium carbonate whiskers were prepared by means of carbonation using active lime as raw materials. The effect of the ration of magnesium to calcium, reaction temperature, stirring speed and the ventilation of carbon dioxide on the synthesis of calcium carbonate whiskers was studied. The result shows that the reaction time has the biggest influence on the synthesis of calcium carbonate whiskers, then the ratio of magnesium to calcium and the ventilation of carbon dioxide,and finally the stirring speed. When the ration of magnesium to calcium is 2,the reaction temperature is 80℃. ,the stirring speed is 100 ~ 130r/min and the ventilation of carbon dioxide is 70 ~ l00mL/ min,the uniform aragonite calcium carbonate whiskers with the length of 25 ~30 μm,the ration of length to diameter about 28 can be obtained.关键词
