Exploratory corrosion tests on materials and fluids for advanced high-temperature molten-salt storage
Applications for high-temperature molten salts in solar energy storage systems are presented and literature is reviewed on the corrosion of ceramics and alloys in molten carbonate, molten chloride, and molten hydroxide. The results of exploratory corrosion studies in these salts at 900/sup 0/C for up to 21 days are presented. Sixteen metal alloys and eight ceramic materials are evaluated. The carbonate salt results in the lowest corrosion rate for alloys in the three salts investigated and also gives low corrosion rates for ceramics. The metals showing the best corrosion resistance are Cabot 600 or Inconel 600, Cabot 800H, Haynes 556, Cabot 214, nickel, and Hastelloy N. The ceramics showing the best corrosion resistance are high-purity alumina and zirconia.
