... with moisture-based contaminants. Thus, the metal wastage could be attributed to the formation of volatile sulfur compounds in the form of potassium pyrosulfate (K 2 S 2 O 7 ). Potassium pyrosulfate has a melting point as low as 427 °C (801 °F) along with high chemical activity. This formed molten slag over...
