Sources of Beryllium Metal and Extraction Locations

Beryllium Extraction. Only three countries, the United States, China and Kazakhstan, currently process commercially viable quantities of beryllium ores and concentrates into beryllium products. Today, the extraction of beryllium begins with the mining of raw materials (bertrandite ore and/or beryl ore).

Physics and chemistry of beryllium - Materion

2014-10-10  Beryllium, atomic number 4, is a silver gray metal of low density (1.85 g/cm3), moderately high melting point (1287°C), and quite good stability in the atmosphere. Favorable mechanical properties, particularly specific stiffness (Young’s modulus/density), have resulted in a number of aerospace applications including major components on the Space Shuttle. The nuclear properties of beryllium are favorable resulting in the use of the metal in test reactors as a neutron reflector and the genera-tion of the present interest in beryllium
