Abstract：Based on the properties of inorganic flame retardants of magnesium hydroxide, the flame retardant mechanism of magnesium hydroxide was introduced. According to the different of raw materials used to preparing magnesium hydroxide, the characteristics of different process for preparing magnesium hydroxide were analyzed. In order to improve the flame retardant performance of magnesium hydroxide and the polymer composite materials, the ultrafine or nano-sized particle preparation, surface modification and encapsulation modification of magnesium hydroxide powders were discussed and the research progress of magnesium hydroxide applied in flame retardants was summarized. The application trend of magnesium hydroxide used as flame retardants was reviewed and prospected.
