研究了搅拌速度、反应温度和镁钙离子浓度比三种工艺参数对碳酸钙结晶习性的影响．指出反应温度的升高有利于碳酸钙以文石相结晶，但在无镁离子存在的高纯原料情况下，并不能使文石相碳酸钙形成；镁钙离子浓度比是影响碳酸钙结晶习性的决定性因素．
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.
