Abstract

507,277. Iron powder. DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT VORM. ROESSLER. Sept. 20, 1938, No. 27431. Convention date, Sept. 23, 1937. [Class 72] [Also in Group III] In the production of iron powder by the reduction of iron oxide by hydrogen, powdered iron is moistened with water in the presence of small quantities of an iron halide and exposed to the action of the air, preferably with stirring, a moderate temperature, say 120-200‹ C., being maintained, the oxidation product so obtained being reduced by hydrogen at 500-600‹ C. Before its reduction, the oxidation product may be heated to 350-400‹ C., preferably in the presence of air, say in a rotary furnace. The iron halide is preferably ferrous chloride, and it may be produced by adding ammonium chloride or hydrochloric acid to the powder when it is moistened. The resultant iron powder is of great fineness and reactive capacity and of very, low bulk weight. Its content of metallic iron may be raised by subjecting it to a second reduction with hydrogen.
