利用氢氧化钙悬浮液碳化方法，通过加入不同形状的控制剂，合成了板状、球状、针状、立方体、链状和纤维状等形状的碳酸钙，研究了碳化过程中晶形rn控制剂种类、加入时间和氢氧化钙悬浮液浓度等因素对碳酸钙晶体形状和大小的影响及碳酸钙合成机理．结果表明，晶形控制剂及加入时间是影响碳酸钙形状的rn主要因素．“,”Calcium carbonate particles with different shapes including plate,sphere,needle,cube,chain and fiber were synthesized by using thern method of carbonation affected the shapes and size of calcium carbonate particles. The experiments indicated: The additive and time to add rnit were key factors that affected the shapes of calcium carbonate particles.
