摘要：

The nanosized particles of LiF were successfully prepared via liquid synthesis method with ammonium fluoride and lithium hydroxide as raw materials, anhydrous ethanol as solvent and crystallization-controlling agent. The structure and morphology of LiF particles were characterized by means of XRD, SEM, TEM and particle size analyzer. The precursor mainly composes of LiF, NH4F and LiOH•H2O. The thermal analysis of the precursor indicates that the decomposition temperature of ammonium fluoride is about 190℃. Nano-powders of LiF has a single cubic crystallographic structure after calcinations at 220~400℃. The nano-LiF particles with average size of about 80nm are full in crystallinity, uniform in size and good in shape. © All right reserved.
