Abstract The properties and fundamental methods of preparing metallic beryllium are discussed on the basis of results obtained by Soviet authors. Comparison is made between thermal reduction of beryllium fluoride by magnesium, electrolytic extraction, and purification of beryllium by distillation in vacuum. Preparation of beryllium articles by different methods of powder metallurgy, melting in vacuum induction furnaces with centrifugal casting, extrusion of beryllium articles and the structure and properties of compact beryllium are discussed. It is found that the maximum tensile strength of pure beryllium samples extruded from a metal hot∞ pressed in vacuum is about 20 kg/mm2 at 425 ° C and that at this temperature the samples possess high plasticity (over 20% elongation).
