摘　　要：以吐温-80为表面活性剂,采用气相扩散技术制备出不同晶型的碳酸钙样品。获得的样品试用X-射线衍射（XRD）、和扫描电镜（SEM）等手段进行表征。结果表明,碳酸钙材料的物相组成和形貌与溶液中吐温-80体积含量和体系温度密切相关。在含有吐温-80的情况下,在30~50℃的范围内,获得的产物几乎全为球霰石;当温度达到70℃,部分产物转变为文石。实验结果的获得对制备该类材料提供了有益的实践参考。Calcium carbonates in different crystallines were synthesized by the vapor-diffusion technology. The obtained products were characterized by X-ray diffraction （XRD） and scanning electron microscopy （SEM）. The results demonstrated that the phases and morphologies of calcium carbonate materials are closely related with the volume ratios of Tween-80 as well as the temperatures. The finding of this paper could be helpful in the controlled synthesis of other materials.
