Abstract A facile method to synthesize the magnesium hydroxide (Mg(OH)2) particles with petal-like morphology was proposed. In this method, we firstly used the sulfate ions as the additives to control Mg(OH)2 particle morphology. The effects of operation parameters, such as reaction temperature, type and concentration of the additives on morphology of Mg(OH)2 particles were investigated. The synthesized sample was thoroughly characterized by X-ray diffraction (XRD), surface area measurement (BET), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), transmission electron microscopy (TEM), selected area electron diffraction (SAED), Fourier transform infrared (FT-IR) spectroscopy, UV–Visible spectra, and particle size distribution. The possible growth mechanism of petal assembly was also discussed for the Mg(OH)2 particles.

添加硫酸根离子制备花瓣状氢氧化镁颗粒

摘要 提出了一种合成花瓣状氢氧化镁(Mg(OH)2)颗粒的简便方法。在该方法中，我们首先使用硫酸根离子作为添加剂来控制 Mg(OH)2 颗粒形态。研究了反应温度、添加剂的种类和浓度等操作参数对Mg(OH)2颗粒形貌的影响。合成的样品通过 X 射线衍射 (XRD)、表面积测量 (BET)、扫描电子显微镜 (SEM)、能量色散 X 射线光谱 (EDS)、透射电子显微镜 (TEM)、选区电子衍射进行彻底表征(SAED)、傅里叶变换红外 (FT-IR) 光谱、紫外-可见光谱和粒度分布。还讨论了 Mg(OH)2 颗粒的花瓣组装的可能生长机制。
