Aragonite calcium carbonate was synthesized by carbonation process, and MgCl/sub 2/ was selected as inhibitor of calcite phase. The effects of concentration of MgCl/sub 2/, pH value of initial suspension, reaction temperature and stirring rate on calcium carbonate polymorphs were investigated. The result indicated that the aragonite phase can be formed at the condition of pH/spl sim/9, above 60/spl deg/C and suitable concentration. The crystal has high aspect ratios ranging from 10 to 40, and can be modified by changing the conditions of reaction.
