Abstract

In this study, Super fine magnesium hydroxide was synthesized by direct precipitation method. The influence of factors, such as reaction time, reaction temperature, solution concentration and the additive amount of dispersing agent on the particle size of MH were investigated. The properties of prepared Mg(OH)2 were studied by Laser particle size analyzer, X-ray diffraction(XRD). The results of XRD showed that the prepared Mg(OH)2 with two kinds of dispersing agent has the same structure compared to the typical Mg(OH)2. The average particle size is about 200nm. The study indicated that the ethanol and PEG6000 as the dispersing agent can obviously reduce the average size of samples by preventing particles reunion. From the point of view of economic and environmental protection, PEG6000 is better to used as the dispersing agents for preparating super fine magnesium hydroxide.
