I.Description/Applications
China is rich in brine resources, and this series of products are prepared by the brine method MgCl2+2NH3·H2O→Mg(OH)2↓+2NH4Cl. It has the characteristics of high purity, good whiteness and controllable particle size.High-purity ultra-fine magnesium hydroxide is a high-purity magnesium hydroxide ultra-fine powder with an average particle size of 1.5µm, 3µm, 5µm and other different specifications obtained by fine grinding and classification processing.
