摘要

The nanograde particles of magnesium hydroxide [Mg(OH)2] with needle-like and disk-like morphologies were synthesized via a simple wet precipitation method. The effects of operation parameters, such as ammonia concentration, Mg~(2+) concentration, reaction temperature and ageing temperature on morphology of magnesium hydroxide nanoparticles were investigated. The samples were characterized by transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR) and X-ray diffractions (XRD). The influence process and growth mechanism were discussed in details.
