... and 1700 °F). High-temperature hot corrosion is caused by the formation of alkali metal salts, such as sodium sulfate (Na 2 SO 4 ) and potassium sulfate (K 2 SO 4 ), which melt and form a liquid on the surface. This molten salt attacks the oxide scale, destroying the protection normally afforded...
