以十二烷基苯磺酸钠(SDBS)和聚乙烯吡咯烷酮(PVP)为模板剂，采用控制反应沉淀法首次合成了中空碳酸锶球。采用扫描电子显微镜、透射电子显微镜、氮气吸附-脱附、X-射线衍射仪、能量色散X射线能谱、傅立叶变换红外光谱、热重分析和差示扫描量热仪等对样品进行了表征，结果表明，在最佳反应条件下，合成的中空碳酸锶球为片状颗粒，尺寸约为2µm。对中空碳酸锶球的形成机理进行了初步探讨。
The hollow strontium carbonate pompons was synthesized for the first time by a controlled reaction precipitation method with sodium dodecyl benzene sulfonate (SDBS) and polyvinyl pyrrolidone (PVP) work together as template. The sampled particles were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), nitrogen adsorption-desorption measurement, X-ray diffraction (XRD), Energy dispersive X-Ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FTIR), Thermogravimetric analysis and differential scanning calorimetry (TGA-DSC),etc. It is shown that the assynthesized hollow strontium carbonate pompons with the size of about 2 µm consist of flake-like particles under the optimal reaction conditions. The formation mechanism of hollow strontium carbonate pompons was preliminarily explored.
