| 摘 要： | 以NH4F和LiOH·H2O为原料、无水乙醇为溶剂和结晶控制剂，采用液相法合成前驱体低温烧结制备纳米级LiF粉末。利用X射线粉末衍射、扫描电镜、透射电镜和激光粒度仪等分析手段对样品进行表征。结果表明，前驱体的主要成分为LiF、NH4F和LiOH·H2O；热分析结果表明，NH4F的分解温度约为190℃。在220~400℃烧结后得到的样品具有单一的LiF立方晶体结构，颗粒饱满，大小均匀，形貌良好，粒径的平均尺寸为80 nm。

| Abstract: | 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°C. 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. |
