| Abstract: | Nanometer-leveled and flake-shaped magnesium hydroxide,with even particle size and fine dispersion,is synthesized by use of direct precipitation method.Magnesium chloride and ammonia are used as raw materials and PEG as dispersant.Effects of reaction temperature,reaction time,concentration of magnesium chloride and ammonia,and reactant mol ratio on the particle size are studied.Morphological structure of the particle is characterized by means of transmission electron microscopy(TEM) and X-ray diffraction(XRD). |
