以无水碳酸钠、氯化钙为原料，磺化脱氢松香酸单钠盐为模板，油酸为有机质，制备了中空球形碳酸钙。采用 SEM 分析其形貌，碳酸钙为中空球形结构，球形粒径为2～3μm，中空直径约为1μm。 FTIR、TG 分析表明有机质已成功对碳酸钙表面进行了修饰，XRD 的分析表明，碳酸钙为球霰石与方解石混合晶型。半定量方法分析得出，球霰石型与方解石型碳酸钙的摩尔分数分别为81．1％和8．9％；碳酸钙与水的接触角为95°，具有较好的疏水性能。

@@@@The hollow sphere calcium carbonate was prepared by using sulfodehydroabietic acid based monosodium salt as tem-plates.During the preparation, anhydrous Na2 CO3 and CaCl2 were used as starting materials and oleic acid was used as or-ganic materials.By SEM, the prepared calcium carbonate is hollow sphere particles with the diameter of 2 to 3 μm, while the diameter of the hollow part is about 1 μm.By FTIR and TG, the surface of calcium carbonate is decorated by organic materials.By XRD, the hollow sphere calcium carbonate contains both vaterite and calcite structure.The contents of va-terite and calcite are 81.1% and 8.9% by semi-quantitative analysis, respectively.The contact angle of this hollow sphere calcium carbonate with water is 95°, therefore, the calcium carbonate has good hydrophobic function.
