| Abstract: | Nano-SrCO3 microspheres was prepared by anionic surfactant-assisted solid phase ball milling,using strontium chloride hexahydrate(SrCl2·6H2O)and ammonium bicarbonate(NH4HCO3)as raw materials and sodium dodecyl benzene sulfonate(SDBS)as anionic surfactant.The prepared SrCO3 samples were characterized by scanning electron microscopy(SEM),transmission electron microscopy(TEM),energy dispersive spectrometer(EDX),X-ray diffractometer,infrared spectroscopy(FTIR),thermogravimetry and differential scanner(TG-DSC).The results show that the prepared SrCO3 samples are spherical in morphology and 30~70 nm in particle size.And the crystal phase composition is typical rhombic aragonite structure.Spherical nano-SrCO3 powder has the advantages of small particle size,narrow distribution,good dispersion and high purity. |
