Abstract

This article emphasizes the importance of acid/base and the oxidizing character of a fused salt to the corrosion mechanism. It illustrates the important aspects of fused salt corrosion using sodium sulfate system. The article discusses the Pourbaix approach to the study of aqueous corrosion with an emphasis on phase stability diagram for the Na-S-O system at 1173 K. It provides information on electrochemical tests, which help in the understanding of fused salt corrosion. The article expounds the hot corrosion mechanism and concludes with a section on the consequences of salt chemistry on corrosion.
