Abstract: Ultrafine magnesium hydroxide has been widely used in various industries，such as flame retardant，electronic industry，pharmacy，sugar refining，insulation material，and other magnesium salt products.High gravity technology mass transfer performance has been greatly improved than traditional equipment，which will help the preparation of ultrafine magnesium hydroxide.The characteristics of high gravity technology applied in the preparation of ultrafine magnesium hydroxide，the advantages and disadvantages of the modified application，the selection of post-processing method，the performances of the prepared products，as well as the present situation of the application of magnesium hydroxide were introduced respectively.The subsequent development of preparation of modified ultrafine magnesium hydroxide with high gravity technology was also expounded.

Key words: high gravity, magnesium hydroxide, preparation, modification
