Abstract
Calcium carbonate whiskers (aragonite phase) are prepared by blowing C O2 gas into the suspension consisting of Ca(OH)(2)-added MgCl2 aqueous solution. The shape and crystalline phase of CaCO3 depend on the prep aration conditions. The optimum conditions for preparing the aragonite whiskers were determined. The whiskers have high aspect ratios rangin g from 20 to 40 with diameters of 0.5-2 mu m. A simple method for prep aring aragonite whiskers by applying a carbonation process using MgCl2 aqueous solution was developed.
