制备

1.碳酸镁法 在衬铅的反应器中，盛有过量的氢氟酸，在搅拌下加入菱镁矿矿浆，于90～95℃下进行反应。反应生成的氟化镁，经过滤、洗涤、在105℃左右进行干燥，再经粉碎，制得氟化镁成品。其反应方程式如下：

2.用一定量的电导水与99.99%的高纯氧化酶混合，用塑料棒搅拌成糊状，然后慢慢加入高纯氢氟酸（稍过量），搅拌后在水浴中煮5-6h，并不断搅拌。待氧化酶全部转化为氟化镁时，用煮沸的电导水倾析法洗涤两次，吸滤后，沉淀置于铂皿中于电炉上灼烧，不时搅拌，干燥后即得高纯氟化镁。 3.碳酸镁与氢氟酸反应。在聚乙烯烧杯中装入50g 46%的氢氟酸，加入42g水稀释为25%的氢氟酸。将烧杯放在冰水浴中冷却，边搅拌边加入48g碳酸镁，即有氟化镁沉淀产生，脱水后，于400℃干燥，所得氟化镁35g
3. 氟化镁的制法由于所用镁盐的不同而分为（１）碳酸镁法　系用氢氟酸与碳酸镁来制取；（２）氧化镁法　系用氢氟酸与氧化镁反应而得；（３）硫酸镁法　系用氟化钠与硫酸镁反应制得，也可用硫酸镁水溶液和氢氟酸（20%）反应而得。在衬铅的反应器中，盛有过量的氢氟酸（40%），在搅拌下加入200目菱镁矿粉熔于其中，于90℃反应30min，其反应式如下。
反应生成的氟化镁，经过滤、洗涤，并在105℃左右进行干燥，再经粉碎后即得成品。
