Abstract
A simple synthetic method for preparing aragonite whiskers has been de veloped. A suspension of CaCl2-MgCl2-Mg(OH)(2) with pH similar to 9 ha s been prepared by adding Ca(OH)(2) to MgCl2 aqueous solution. CaCO3 w hiskers (aragonite phase) have been prepared easily by blowing CO2-con taining gas into the suspension. The whiskers have high aspect ratios ranging from 20 to 80 with diameters of 0.5-1 mu m.
