| Abstract: | Magnesium hydroxide that was of nanometer level and flake shape and had uniform particle size was synthesized by calcination and hydrochloric acid-acidification and with magnesite as raw material. Investigation was made on the best technological conditions for nanometer magnesium bydroxide preparation, including the best reaction temperature and time, the initial reaction concentration of magnesium ion and the effect of mole ratio of magnesium ion to oxy-hydrogen root ion on the shape appearance and size of product. The crystallization oxy-hycirogen root ion characteristic of nanometer magnesium hydroxide was analyzed and its crystallization mechanism drawn. Th research results have laid good basis for testing the flame retarding property of magnesium hydroxide. |
