摘　　要：采用溶液法制备了不同晶形碳酸钙,讨论了各种因素对碳酸钙结晶的影响,并得到了粒径较小的球状和片状碳酸钙.实验表明通过加入水溶性高分子聚合物,利用其在固-液界面的吸附特性,可达到抑制晶核生长和改变晶形的目的.A process for the preparation of different particles of CaC03 is intruducted, the effect of various factors on CaCO3 crystal is discussed and spherical and plate-like calcium carbonate with small partical size are obstained. The paper showed that the crystal gorwth is inhibited and Crystal shape is altered by adding ma-cromolecule polymer dissolved in water with their characteristic of absorbed on the interface of solid and liquid during the percipitation of calcium carbonate.
