Effect of Experiment Parameters on the Crystalline Habit of Calcium Carbonate Whisker

Qing Liu

Abstract

The effect of stir speed, reaction temperature and [Mg2+]/[Ca2+] ratio on the crys- talline habit of CaCO3 was studied. It is shown that though the increase of reaction temperature is propitious to the formation of aragonite phase, aragonite phase cannot be formed if there is no Mg2+ existed in solution. Based on the detailed analysis of experimental result, it is concluded that [Mg2+]/[Ca2+] ratio is the key factor for polymorph of calcium carbonate in carbonate process.
