| Abstract: | Both whisker and nanometer MgSO4 @ 5Mg(OH)2 @ 3H2O(MOS) were prepared by hydrothermal method at140℃ for different times, using NaOH and MgSO4 @ 7H2O as raw materials. The MgSO4 @ 5Mg(OH)2 @ 3H2O part-icles were characterized by powder X-ray diffraction(XRD), thermal analysis(TGA-DSC), infrared spectroscopy(FT-IR), transmission electron microscopy (SEM) and scanning electron microscopy (TEM). The size distribution inwhisker-like and nanocrystalline materials are in the range of 10～50μm and 10～20nm respectively. The whiskerMOS is metastable phase in MgSO4-NaOH-H2O system at 140℃, whereas nanometer MOS is stable phase. |
