Abstract

508,028. Beryllium articles; wet separating. DEUTSCHE GOLD-UND SILBER - SCHEIDEANSTALT VORM. ROESSLER. Dec. 23, 1937, No. 35663. Convention date, Jan. 2. [Classes 82 (i) and 82 (ii)] Beryllium articles are made by purifying powdered beryllium by treatment with concentrated nitric acid, freeing the powder from the acid, converting it by compression at high pressures. (e.g. 10-30 tons. per square cm.) into products of the desired shape, and subjecting the shaped products to a sintering process at temperatures from 900-1250‹ C. in an inert atmosphere, preferably in a vacuum. The powder may also be pretreated by subjecting it to gravity separation from beryllium oxide and other oxide particles. Suitable separating agents are ethylene bromide, acetylene tetrabromide, or bromoform, and lighter liquids such as benzene, toluene, or carbon tetrachloride may be added thereto. The invention is suitable for sheets, discs, cylinders, and thinwalled articles.
