Fe2O3-, Fe3O4-, NaOH-Fe2O3-, and NaOH-Fe3O4-coated substrates of Vycor and of iron were exposed to controlled gas mixtures containing SO2 and SO3. Sulfate and sulfide formation are examined and explained on thermodynamic grounds. Examination of the role of MgO coatings indicates a limited “protective” effect through its removal of SO3 from the gas stream.
