Beryllium

The content of beryllium in nature is 6ppm. The most common beryllium deposits include beryl, beryllium silicate and garnet. Beryllium is produced by electrolyzing molten beryllium chloride. Beryllium can be obtained by electrolyzing beryllium fluoride with fluorides of alkali metals or alkaline earth metals to form M2BeF4 or MBeF4 type molten salts. The purity can reach 99.7%. Beryllium can also be produced by making molten salts of beryllium chloride and chlorides of alkali metals, and then electrolyzing them to obtain beryllium, with a purity of over 99.8%. If a product of higher purity is required, vacuum distillation can be used for purification. Place the product obtained through electrolysis in a vacuum distillation apparatus. When starting distillation, it is important to note that the container should not be sealed at first, as the crude product contains electrolytes, alkaline earth metals and gases. During heating, it may spill. After the gases are discharged and the molten metals have stabilized, the container should be sealed and vacuumed until a high vacuum is reached. Then, heat to 1400 to 1500 degrees Celsius for distillation. After about 20 minutes, stop heating when about 1/4 of the crude product remains. The purity of the product can reach 99.97%.
