铍粉
铍粉用途
用来制造核反应堆中的热交换器。铍还用做原子反应堆中的中子减速剂和反射层。高纯度铍是快中子的重要来源。铍透X射线能力最强，有金属玻璃之称。用来制造X光管的窗口。铍主要用来制合金如高弹性的铍青铜，制造不发火工具的铜铍镍合金，以及用于制造飞机用的含铍合金。

铍粉制备
铍在自然界中含量为6ppm。最常见的铍矿有绿柱石、铍硅石、光榴石。电解熔融的氯化铍制取铍。铍可由氟化铍与碱金属或碱土金属的氟化物制成M2BeF4或MBeF4类型的熔融盐，然后进行电解而得到。纯度可达99.7%。也可由氯化铍与碱金属的氯化物制成熔融盐，再电解而制得铍，其纯度可达99.8%以上。
精制方法如果需要更高纯度的产品，可以用真空蒸馏法提纯。将电解得到的产品置于真空蒸馏装置中。开始蒸馏时需注意，容器先不要密封，因为粗品中夹带有电解质、碱土金属和气体，加热时会崩溅，等气体排出，熔融的金属平稳下来之后，再密闭容器，抽真空，至到达高真空时，加热1400～1500℃进行蒸馏，约20min后，待粗品剩余约1/4时停止加热，产品的纯度可达99.97%。
