Technological Study on Preparation of Calcium Carbonate Whiskers by Using Active Lime

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 ...
