Synthesis and Characterization of Hollow Strontium Carbonate Pompons by Composite Soft Template Method

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.
