Abstract
809,936. Electrolysis. LIBBEY OWENS FORD GLASS CO. Aug. 27, 1956 [Sept. 7, 1955], No. 26074/56. Class 41. A method of at least partially removing an electrically conductive metal oxide film 12, e.g. tin oxide from a non-conductive surface 10, e.g. of glass, provided with an electrode, comprises contacting the film 12 with an aqueous solution of an electrolyte 14 and establishing a voltage between the film 12 and the electrolyte. In deleting tin oxide 12 from a glass pane 10, the electrolyte, which may be an acid, base or salt, may be presented to a restricted area of the film 12 by masking the film 12 or by applying the electrolyte by a draughtsman's pen 13 which is connected at 15 to a voltage source, the other terminal of which is connected at 16 to a bus-bar 11 fired on to the glass 10. The electrical connections may be such as to make the film 12 the anode or cathode, or A.C. may be employed. In another example, the sheet 10 is immersed edgewise in an electrolytic bath, and the sheet 10 may be immersed at constant velocity to provide a graded removal of the film 12. Electrolytes mentioned are hydrochloric, sulphuric and phosphoric acid, the hydroxides of sodium, potassium and ammonium, and ammonium or sodium chloride and sodium sulphate. Voltages of 0.7 to 24 D.C. are mentioned. The electrolytic action in the case of acid and salt electrolytes is to reduce the tin oxide to tin, which remains on the glass 10 when a salt electrolyte is employed, but is dissolved by an acid electrolyte. A base electrolyte is thought to reduce the tin oxide to a soluble stannite.
