Evolution of Stibine at Antimony Cathodes

Abstract
A technique is described for determining the relation of the microstructure of lead and its alloys to the anodic corrosion occurring in sulfuric acid. This method has been used to show the manner in which the corrosion of lead and of its hypoeutectic antimony alloys is related to their microstructures. It was found that pure lead and the lower alloys corrode by intercrystalline attack, and that the higher alloys corrode by penetration of the antimony‐rich network.
