以白云石为原料成功地合成了沉淀碳酸钙。研究了碳化温度和碳化速率对碳化产物形貌、晶粒尺寸、物相和结构的影响。由该方法产生的颗粒具有400-800 nm的晶体尺寸。在30°C碳酸化速率为2和7 SCFH时生成方解石相，在80 °C碳酸化速率为2 SCFH时也生成方解石相。通过SEM观察显示方解石的形态为所谓的鲨齿面体。
The precipitated CaCO3 has successfully been synthesized from dolomite. The influence of various temperature and carbonation rate on the morphology, crystal size, phase and structure of the carbonation products were studied. The particles resulted from this process have the crystal size 400-800 nm. The calcite phase wasformed inthe synthesis at 30°C with carbonation rate of 2 and 7 SCFH, and synthesis at 80 °C and 2 SCFH also produces calcite phase. Observations by SEM shows morphology of calcite as so-called schalenohedral.
