Abstract
836,731. Electro - deposition of metals. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 27, 1956 [Dec. 30, 1955], No. 39300/56. Class 41. A process for the electro-deposition of a layer of a metal upon a conductive cathode surface is characterized in that a mass of an inert absorbent material is wetted with a solution of the metal to be deposited and is sandwiched between an anode and the cathode surface, a current is passed from the anode to the cathode through the said mass to effect deposition of the desired layer and the mass of inert absorbent material is washed to remove solution from it whilst the current is continued. The process may be used for depositing layers of rare metal (i.e. metal in short supply) such as zirconium, masurium, rhenium, and all elements heavier than bismuth, and also radio-active metals such as F e 55, Zn<SP>59</SP>, Au<SP>195</SP> and enriched isotopes such as Fe<SP>54</SP>, Cu<SP>65</SP> and Ag<SP>109</SP>. Suitable inert absorbent materials are gels, such as silicon. dioxide, pectine, hydrated starch and gelatine, and also filter paper, asbestos layers, porous sintered ceramic material and glass fibres. The anode may be of graphite or a rare metal. The metal layer may be deposited not only on metals hut also on synthetic resins which have preliminarily been covered with an electrically conductive layer consisting, e.g. of graphite or silver. As shown, a gelatine layer 1, wetted with a solution of Fe<SP>55</SP>Cl 3 in hydrochloric acid is provided on graphite anode 2 secured to metallic electrode 3. Copper plate 4 of size and shape similar to that of the upper surface of layer 1 constitutes the cathode and is secured to electrode 5. Cathode 4 is pushed against layer 1 by handle 6 and a voltage is applied between anode and cathode. Subsequently the anode, cathode and layer 1 with voltage still applied are sprayed with water from tube 10 through apertures 11. Spraying is continued as the electrodes are separated, the separation stopping the current flow. The waste water 12 is collected in vessel 14 through aperture 13.
