Process parameters optimization of Direct synthesis nano magnesium fluoride powders

摘要

To reduce average particle size,magnesium fluoride was directly synthesized from MgF2and NH4F,the product was characterized by X-ray diffractomer,scanning electron microscopy.Orthogonal experiment was used to explore the influences of factors on the average particle size.Found that the effect order of factors on the average particle size is MgCl2 concentration,NH4F concentration,reaction temperature,reaction time,in the optimization of process conditions,average particle size is 23.1 nm.
