高纯纳米氟化锂的制备方法
摘要：
高纯纳米氟化锂的制备方法，以工业氯化锂和氟化氢铵为原料，氯化锂经水溶解、萃淋树脂色层法纯化、浓缩、喷雾干燥得到高纯无水氯化锂；氯化锂经氟化氢铵干法合成氟化锂。本发明相对于提纯碳酸锂、氢氧化锂等锂化合物而言，工艺简单、操作方便；采用干法合成氟化锂，引入杂质少，含水量低；合成与分离纯化在同一设备中分步完成，缩短了工艺流程，操作方便。采用本发明获得的高纯氟化锂产品为具有纳米介孔结构的类球形纳米晶聚结体，活性高。
摘要（英）：

The invention discloses a preparing method of high-purity nanometer lithium fluoride, which comprises the following steps: adopting industrial lithium chloride and ammonium hydrogen fluoride as raw material; dissolving lithium chloride in the water; purifying through extracting sprinkling resin chromatographic method; condensing; spraying; drying to obtain high-purity anhydrous lithium chloride; making lithium chloride synthesize lithium fluoride through ammonium hydrogen fluoride drying method. The invention introduces little impurity with low water content, which produces high-activity ball-shaped nanometer crystal coalescencer.
