Influence of polyvinylpyrrolidone on morphology and dispersity of magnesium hydroxide

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,dispersity 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 dispersity.
