Abstract:

Magnesium hydroxide nanoparticles were synthesized in one step via  bubbling gaseous ammonia into magnesium chloride solution without any modification. The samples were characterized with scanning electron microscope (SEM), X-ray powder diffraction (XRD), and thermal gravimetric analysis-differential thermal analysis (TG-DTA).The influence of reaction time and temperature on the morphology of Mg(OH)₂ nanoparticles was investigated by experiments, and based on the reaction process of bubbling gaseous ammonia into magnesium chloride solution, the morphology and growth mechanism of Mg(OH)₂ nanoparticles were analyzed and discussed. It will be widely used in industry due to its simple process and special morphology.
