Abstract
The rates of combination of sulphur dioxide and oxygen at a mild steel surface at various temperatures with dry and moist gases have been measured. Sulphide and sulphate formation is found to occur simultaneously, the sulphide being concentrated near to the surface of the basis steel. The rate of sulphate formation is greatest between 580° and 635° corresponding to the maximum catalytic activity of Fe O~a~. Water vapour inhibits sulphide and sulphate formation, but increases the rate of oxidation.
