| Abstract: | High temperature Pourbaix-type thermodynamic phase stability diagrams for Na-M-S-O systems are established. The solubility of metal oxides in fused Na_2SO_4 measured in the past few years are reviewed and explained in terms of thermodynamic phase stability diagrams. The activity coefficients of soluble metal species in fused Na_2SO_4 are also given. The fluxing mechanism of hot corrosion induced by the deposit of molten Na_2SO_4 are discussed in the light of the dissolution behavior of metal oxides in fused Na_2SO_4. |
