| Abstract: | A simple synthetic method for preparing aragonite whiskers has been developed. A suspension of CaCl2-MgCl2-Mg(OH)2 with pH ～9 has been prepared by adding Ca(OH)2 to MgCl2 aqueous solution. CaCO3 whiskers (aragonite phase) have been prepared easily by blowing CO2-containing gas into the suspension. The whiskers have high aspect ratios ranging from 20 to 80 with diameters of 0.5–1 μm . |
