参考 B.P.美国专利号 781,100 描述了一种生产铍的方法，其中预先粉碎的氟化铍和细碎的镁按化学计量比例压制成直径约 2 英寸、深度约 1 英寸的团块。将团块放入熔融氯化钙浴中，然后将装有氯化钙的容器密封，并将内容物在高温下加热一到两个小时。随后，发现该方法的成功并不限于使用熔融氯化钙作为浴的材料。根据本申请，其他合适的熔融材料是：氯化镁、氯化钠、氯化钠和氯化镁的混合物、氯化铍和氯化钙的混合物、以及氟化钙和氟化钠的混合物。
Reference is made to B.P. 781,100 describing a method of producing beryllium whereby previously crushed beryllium fiuoride and finely divided magnesium are compacted in stoichiometric proportions into briquettes of about 2 in. diameter and 1 in. depth. The briquettes are placed into a bath of molten calcium chloride, the vessel holding the calcium chloride being sealed afterwards and the contents being heated at elevated temperature for a period of one to two hours. Subsequently, it has been found that the success of the method is not restricted to the use of molten calcium chloride as a material for the bath. According to the present application other suitable melt materials are: magnesium chloride, sodium chloride, mixtures of sodium and magnesium chlorides, mixtures of beryllium and calcium chlorides, and mixtures of calcium and sodium fluorides.
