The Influence of Crystal Face on the Electrochemical Properties of a Single Crystal of Copper

Abstract
The importance of crystal face in several electrolytic processes in a copper sulfate‐sulfuric acid solution has been investigated with the aid of electrolytically polished single crystals of copper. The processes studied consisted of simple chemical etching, electroetching, electrodeposition, action of an alternating current, action of an alternating current superimposed on a direct current, and electrolytic replacement. It was found that all of these processes were influenced greatly by the crystal face exposed at the surface. The nature of the surrounding atmosphere was found to influence the physical form of the electrodeposit.
