Surfactants-Controlled Morphosynthesis of Strontium Carbonate

Abstract:

Article Preview

The controlled synthesis of SrCO3 microstructures with different morphologies, such as flower-like, cauliflower-like and finger-like, were successfully achieved in the presence of mixed nonionic/anionic surfactants polyoxyethylene (20) sorbitan monolaurate (Tween20) and sodium dodecyl sulfate (SDS). Results indicated that SDS/Tween20 complex micelles played important roles in the morphological control of SrCO3 microstructures. Also, the influence of CO32- concentration on the morphology of SrCO3 crystals was investigated and discussed. X-ray powder diffraction (XRD), fourier transform infrared spectroscopy (FT-IR) and field-emission scanning electron microscope (FE-SEM) were used to characterize the as-synthesized crystals.
