| Abstract: | The influence of technological conditions on the particle size and the appearance of magnesium hydroxide was inspected. The results showed that powder of nano - sheet magnesium hydroxide could be prepared with good crystallization, high purity, particle size of 35 nm, uniform size and good dispersion under the optimum reaction conditions as follows： the concentration of ammonia water 6.02mol/L, the ratio of concentration of magnesium ion to the hydroxide ion 1 ： 1.7, reaction temperature 75 ℃, reaction time 65 min, initial concentration of magnesium ion 1.1 mol/L, and the content of surfactant 0.1%. |
