摘要: 建立了高温Pourbaix型Na-M-S-O系热力学相图,总结了近年来金属氧化物在熔融Na_2SO_4中的溶解度的研究结果,并用高温Na-M-S-O系相图予以解释,还给出了有关金属溶解形式在熔融Na_2SO_4中的活度系数。基于金属氧化物在熔融Na_2SO_4中的溶解行为的研究结果,讨论了由熔融Na_2SO_4引起的热腐蚀的盐溶模型。

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.
