ABSTRACT: Nanometer magnesium hydroxide was prepared by positive drop method using magnesium chloride hexahydrate as raw material and sodium hydroxide as precipitant, and its preparation process was optimized. The results of single factor experiments show that the optimized process conditions are as follows: reaction temperature 40°C, stirring speed 900 rpm, initial concentration of magnesium chloride C = 1 mol/L, concentration ratio of magnesium chloride to sodium hydroxide solution n (Mg2+): n (OH-) = 1:2, reaction time T = 60 min, drop acceleration of sodium hydroxide solution 2 ml/min.
