Title: Process for the manufacture of metallic beryllium or its alloys by means of the electrolysis of a molten mass
IPC: C09B1/467
Filed: 1927-10-06
Abstract: 278,723. Siemens & Halske Akt.-Ges. Oct. 7, 1926, [Convention date]. Beryllium and its alloys, obtaining.-Beryllium and its alloys are obtained by electrolysis of a molten mass containing basic beryllium fluoride or beryllium oxyfluoride or both; further quantities of these compounds are added as electrolysis proceeds. Basic beryllium fluoride is obtained by evaporation of a solution of beryllium oxide in hydrofluoric acid, the residue being dried at 350-400‹ C. ; it contains 21-23 per cent beryllium. Beryllium oxyfluoride is obtained by strongly heating the basic fluoride; its beryllium content is greater than 23 per cent. The electrolyte contains in addition alkaline earth metal fluorides and may also contain alkali metal fluorides. In an example, a mixture of barium fluoride and beryllium oxyfluoride is melted by the electric arc in a graphite crucible. The product is heated to 1200‹-1350‹ C. and electrolyzed, using a water-cooled cathode. Volatilized salts are trapped by means of a dust chamber or on continuous current high tension electrodes, and are returned to the bath either alone or with fresh beryllium oxyfluoride. The beryllium regulus separated at the cathode is removed from time to time. Alloys are obtained by deposition into a molten cathode consisting of the alloying metal. Articles may be coated with beryllium by introduction into the bath as cathodes, being cooled if necessary. They may be first coated with tungsten, molybdenum, tantalum, vanadium or niobium or with iron, copper, nickel, cobalt, cobalt or other metal. The subsequently deposited beryllium may in some cases diffuse into the intermediate layer. In coating articles, the temperature of the bath may be 700‹-1200‹ C. Coatings of alloys may be obtained by adding a salt of the alloying metal e.g. aluminium to the molten electrolyte. Alloys with copper, magnesium, nickel, cobalt and iron may be deposited. Specification 192,970 is referred to.
