A Method of Preparing Thin Gold and Silver Foils of Uniform Thickness by Electrolysis

摘要

Gold and silver single-crystal foils of uniform thickness have been produced by electrolysis. The preparation of gold foils involves three steps: the evaporation of silver onto cleaved mica, the electrodeposition of gold on silver, and, lastly, the stripping of the gold foil by dissolving the intermediate layer of silver. Silver foils are prepared by (1) evaporating silver onto cleaved mica, (2) electrodepositing silver on silver, and (3) mechanically stripping the silver foil.
