“…Magnesium oxysulfate whiskers have attracted attention because of their distinctive properties, such as low density, high elastic strength, high melting point and high modulus of rupture (Schierding & Deex, 1969;Yuan, Wong, & Wang, 1995). Basic magnesium sulfate (5Mg(OH) 2 ·MgSO 4 ·3H 2 O, abbreviated as 513MOS) whiskers are a type of magnesium oxysulfate whisker that can be used as a material reinforcing agent, a flame retardant for wooden materials, and a composite material additive for rubber and ceramics (Lu et al, 2004(Lu et al, , 2006Wei, Qi, Ma, & Bao, 2002).…”

Due to the special topography in length and diameter, magnesium oxide (MgO) whisker has good mechanical properties to improve the mechanical and biological properties of biodegradable polymer materials, while the morphology of MgO whisker is significantly related to the morphology of its precursor whisker. In this work the precursor whisker is prepared through the mild solution approach and the effects of three producing factors on the growth of precursor whisker are systematically investigated by scanning electronic microscopy (SEM) and X-ray diffraction (XRD). It reveals that the morphology and composition of MgO predominantly dependent on precursor is prominently influenced by the preparing parameters, especially in solution concentration, aging time and aging temperature. The suitable preparing conditions in present experiment are with 0.6mol/L solution concentration, under 10h aging time and at room temperature, through which the radial dimension of whisker reaches to the nanolevel and the optimal aspect ratio is 80:1.

“…As a kind of new multifunctional inorganic material, Magnesium oxide whisker exhibits good heat, insulation, and alkali resistance. It is commonly used as a reinforcing filler for composite materials that widely used in the fields of chemical, ceramic and aerospace applications . The Lop Nur salt lake in China's Xinjiang Autonomous Region contains abundant Mg resources, mainly MgCl 2 and MgSO 4 (>1.1×1010 t).…”

Four methods including hydrothermal method, glycolhydrothermal method, microwave-hydrothermal method and glycol-microwave-hydrothermal method were used to prepare magnesium oxide precursor by the reaction of MgSO 4 ·7H 2 O with (NH 4 ) 2 CO 3 . The composition, crystallinity, morphology, aspect ratio, yield, functional groups, atom distribution, and interplanar spacing of the sample were investigated by X-ray diffraction (XRD), Scan Electron Microscope (SEM), Fourier Transform Infrared Spectroscopy (FT-IR), and High Resolution Transmission Electron Microscope (HRTEM). The properties of Magnesium Oxide precursor were compared with each other. The results of FT-IR and XRD showed that the crystals were all nesquehonite. However, it was shown by FT-IR results that the crystals prepared by glycol-microwave-hydrothermal method contained OH − and HCO 3 − groups, which indicated that the Mg(OH)(HCO 3 )·2H 2 O type crystals would be facilitated by this method. The glycol-hydrothermal method can create high quality Magnesium Oxide precursor with a high degree of crystallinity, high purity, high aspect ratio, smooth surface, and good dispersibility.
