This article discusses two general mechanisms of corrosion in molten salts. One is the metal dissolution caused by the solubility of the metal in the melt. The second and most common mechanism is the oxidation of the metal to ions. Specific examples of the types of corrosion expected for the different metal-fused salt systems are also provided. The metal-fused salt systems include molten fluorides, chloride salts, molten nitrates, molten sulfates, hydroxide melts, and carbonate melts. The article concludes with information on prevention of molten salt corrosion.
