SYNTHESIS OF NANO SIZED MAGNESIUM HYDROXIDE

摘要

PURPOSE: A manufacturing method of nanosized magnesium hydroxide is provided to synthesize magnesium hydroxide with excellent dispersity and crystallinity in short time by using microwaves. CONSTITUTION: A manufacturing method of nanosized magnesium comprises a step of mixing a magnesium salt and alkali source; a step of treating microwaves of the mixture solution; a step of cooling washing the result; and a step of drying the result. Waves with an ultra high frequency of 40-1400W is irradiated to the mixture solution for 5-30 minutes. The mixture solution is one or more of MgSO4, MgCl2, and MgNO3. The magnesium salt is used with a concentration of 0.5-3.0 mol/L. The alkali source is one selected from NaOH, ammonia solution, and amine-based compound.
