![عکس صفحه اول مقاله: Morphology control and growth mechanism of magnesium hydroxide nanoparticles via a simple wet precipitation method Morphology control and growth mechanism of magnesium hydroxide nanoparticles via a simple wet precipitation method](/preview/png/1463018.png)
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, Mg2+ 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.
Magnesium hydroxide nanoparticles with needle, disk-like morphologies were synthesized via a simple wet method, by controlling the process conditions and using PEG-12000 as dispersant and template. The reaction temperature, which influenced the adsorption modes of PEG-12000 on the crystal faces, was an important parameter to control the morphology and particle size of Mg(OH)2.Figure optionsDownload as PowerPoint slideHighlights
