摘　　要：采用复分解反应的方法,通过加入不同的添加剂,合成了分散性良好、具有多孔结构的球状纳米碳酸钙及棒状微细碳酸钙。运用XRD和TEM对产物进行表征和分析,初步研究了反应时间对产物晶型及粒径的影响。The method of double decomposition reaction was used for synthesizing the spherical nanometer calcium carbonate of the good dispersibility and porous structure and clubbed tiny calcium carbonate under joining the different chemical additives in the solution. The TEM and XRD were used for the analysis of the granularity and purity of the nanometer calcium carbonate. The influence of the reaction time to product crystalline form and particle size was researched preliminary.
