Abstract

152,835. Smith, J. D. Sept. 5, 1919. Coating non-metallic surfaces with metals.- A copper-salt solution is reduced by hydrazine hydrate in the presence of ammonia, the copper being deposited as a coherent coating on heated, non-conducting, smooth or polished surfaces, such as glass, china, porcelain, and the like, in contact with the solution. The coating liquid can be prepared by adding strong copper sulphate solution to a strong solution of hydrazine sufphate in hot water until a faint blue colour persists on standing and a pale-blue powder is precipitated. If not for immediate use, the powder may be filtered and dried. When used, it is suspended in cold water, a few drops of cold hydrazine sulphate solution added, followed slowly by a solution of ammonia until the liquid turns darkbrown, when caustic soda solution is added until a slight yellow or orange precipitate persists after shaking. The precipitate is dissolved by a little hydrazine sulphate, yielding the clear yellowish or brownish liquid required.
