Abstract
379,499. Distilling barium and other metals. RADIOAKTIENGES, D. S. LOEWE, 10, Wiesenweg, Steglitz, and BENJAMIN, H., 62, Fasanenstrasse, both in Berlin. Aug. 15, 1931, No. 23018. Convention date, Aug. 15, 1930. Drawings to Specification. [Class 82 (i).] Barium or other metal is vaporized in an electric discharge device from a mixture of a reducing agent and a compound of the metal, the mixture being wrapped under oil in a metallic foil which is coated with a substance, e.g. collodion, insensitive to the atmosphere. The mixture may consist of barium oxide and aluminium or silicon or ferro-silicon, and the foil is formed of aluminium, tin, or zinc. The " pill " may be heated during exhaustion to vaporize the foil and subsequently further heated to generate the vapour.
