| Abstract: Both whisker and nanometer MgSO4·5Mg(OH)2·3H2O(MOS) were prepared by hydrothermal method at 140℃ 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 in whisker-like and nanocrystalline materials are in the range of 10～50μm and 10～20nm respectively. The whisker MOS is metastable phase in MgSO4-NaOH-H2O system at 140℃，whereas nanometer MOS is stable phase. |
