Abstract

1,146,744. Electro-depositing iron. DEUTSCHE AKADEMIE DER WISSENSCHAFTEN ZU BERLIN and INSTITUT FIZICESKOJ CHIMII AKADEMII NAUK SSSR. July 8, 1966, No.30810/66. Heading C7B. Pure iron monocrystals are produced by electro-deposition from an aqueous acid solution containing between 10 and 400 g/1 Fe and of pH between 0À5 and 6, at a bath temperature between 20 and 320‹ C. and current density between 0À05 and 400 A/dm<SP>2</SP>, using a pure iron anode and an electrolytic cell made from or clad with a synthetic resin e.g. P. T. F. E, or a metal resistant to the electrolyte used e.g. Fe or Pt. The cell may be constructed as or housed in an autoclave for operation above 100‹ C. using inert gas to the neccessary pressure. The anode may be in the form of a ring and made from electrolytic and/or sintered carbonyl iron. The cathode may be iron monocrystals (for epitactic deposition) or polycrystalline Fe or Pt. The electrolyte may be made by dissolving pure Fe or a purified ferrous salt.
