摘　　要：CaCO3 hollow spheres were prepared easily in anion surfactants （sodium dodecylbenzenesulfonate （SDBS）） and aspartic （Asp） acid binary-additive system by using an easy rapid agitation method. The as-prepared products were characterized with scanning electron microscopy （SEM）, FT-IR and X-ray diffraction. The results suggested that the CaCO3 hollow spheres have diameters ranging from 1 to 2 μm, and their wall is constituted of many nano-particles. Moreover, the possible formation mechanism of the hollow spherical structure was proposed.CaCO3 hollow spheres were prepared easily in anion surfactants （sodium dodecylbenzenesulfonate （SDBS）） and aspartic （Asp） acid binary-additive system by using an easy rapid agitation method.
