Influence factors of calcium carbonate whiskers prepared by intermittent bubbling method
Calcium carbonate whiskers were successfully prepared in the MgCl2-Ca(OH)2-CO2 system by a intermittent bubbling method and characterized by X-ray diffraction and scanning electron microscopy.The results demonstrated that aragonite style calcium carbonate whiskers with well morphology,large aspect ratio and smooth surface can be obtained by controlling technical conditions such as reaction temperature,concentration of Ca(OH)2 and amount of additives and under the conditions of CO2 flow velocity of 3.4ml/min/gCa(OH)2,flow of CO2 to air ratio of 1∶4,stirring speed of 240 r/min.
