常温常压下，以氨法制备氢氧化镁粉体，添加聚乙烯吡咯烷酮对氢氧化镁进行表面改性，制备片状、花朵状、球状、棒状、带状形貌的氢氧化镁，利用SEM、TEM、XRD等分析了氢氧化镁的形貌、分散性和结晶性。结果表明，简易条件下，通过控制聚乙烯吡咯烷酮的用量，能实现具有不同形貌和良好分散性的氢氧化镁的连续、可控制备。
Magnesium hydroxide of sheet-,flower-,sphere-,rod-and belt-like morphologies were prepared at ambient conditions via ammonia method with the help of polyvinylpyrrolidone (PVP).The morphology,dis-persity and crystallinity of the as-prepared magnesium hydroxide were investigated by means of SEM,TEM and XRD.The results show that a facile method of controllable continuous synthesis of magnesium hydroxide was developed with the help of PVP,in which the products were fabricated with different morphology and good dis-persity.
