Beryllium (Be): Neutron Moderator in Reactors and Alloying Agent for High-Strength Copper Alloys
Beryllium (Be), atomic number 4, belongs to Group 2, Period 2 elements and is the lightest alkaline earth metal. It appears steel-gray, with a melting point of 1283°C, boiling point of 2570°C, and density of 1.848 g/cm³. Natural beryllium has three isotopes: Be-7, Be-8, and Be-10, with ⁹Be being its only stable nuclide.

About Beryllium
Beryllium's natural abundance is 6 ppm. The most common ores are beryl, bertrandite, and phenakite.
Beryllium is produced by electrolyzing molten beryllium chloride. Alternatively, beryllium fluoride can be combined with fluorides of alkali or alkaline earth metals to form M₂BeF₄ or MBeF₄-type molten salts, which are then electrolyzed to obtain beryllium with purity up to 99.7%. Another method involves electrolyzing molten salts made from beryllium chloride and alkali metal chlorides, yielding beryllium with purity exceeding 99.8%.
Refining Method
For higher purity requirements, vacuum distillation is used for purification:
The electrolytically obtained product is placed in a vacuum distillation apparatus. Initially, the container should remain unsealed because the crude material contains trapped electrolytes, alkaline earth metals, and gases that may cause splattering during heating. After gas evolution ceases and the metal stabilizes, the container is sealed and evacuated. Under high vacuum, the material is heated to 1400-1500°C for distillation. After approximately 20 minutes, when about 1/4 of the crude material remains, heating is stopped. The resulting product achieves a purity of 99.97%.
