Corrosion of iron in the presence of dispersed and solid sulphur

Abstract

The observation of Farrer & Wormwell1 that steel is attacked rapidly by aqueous dispersions of sulphur has been confirmed. It has been shown, however, that the corrosion is decreased considerably when the pH of the solution is raised to a value of 9 or lowered to a value of 4. Much less corrosive effects were noted when dispersions of commercial sulphur cements were used in place of elementary sulphur.
