Spherical SrF2 formed with nanocubes was successfully prepared by hydrothermal method,using strontium hydroxide and ammonium fluoride as raw materials,trisodium citrate as complexing agent.The effect of the molar ratio of trisodium citrate to strontium hydroxide,the concentration of strontium hydroxide,and the hydrothermal time on the phase and morphology of the product was investigated,and the formation mechanism was proposed.The morphology and phase of the product were characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD),fourier transform infrared spectroscopy(FT-IR) and X-ray energy spectroscopy(EDS).The results showed that the prepared spherical strontium fluoride had regular morphology and uniform size under molar ratio of the trisodium citrate to strontium hydroxide was 1∶1,the strontium hydroxide concentration of 0.08 mol/L and the hydrothermal time of 6 h,the trisodium citrate added in the process played an important role in the formation of the spherical structure.
