Abstract
324,415. Levy, L. A., and Almeida Accumulators, Ltd. Oct. 30, 1928. Amalgamating.-A cathode which receives a deposit of zinc during charging is provided with a coating of zinc mercury alloy by immersing it in a bath of the molten alloy. The latter may be prepared by adding 4 parts of electrolytic zinc to 5 parts of mercury heated to 370‹ C., the mixture being covered with melted zinc chloride to which a small quantity of ammonium chloride is added. The cathode may consist of sheet iron. Before immersion in the molten alloy the iron is freed from grease and pickled. The grease may be removed by a solvent such as trichlorethylene, the iron being then de-oxidized bv heating in hydrogen. The cleaned iron may then be plunged in the bath of alloy or it may be further treated by immersion in a molten bath consisting of a mixture of sodium chloride, carbonate and cyanide. After the iron has been removed from this bath, the layer of salts may be dissolved off in a hot solution of caustic soda before the iron is plunged in the hot alloy bath. Another example of the latter comprises 85 per cent of mercury and 15 per cent of zinc heated to 250‹ C.
