Abstract Scope |
Much data exists for the diffusion and solubility of chromium in molten fluoride salts, originally gathered during the Aircraft Nuclear Reactor Experiment. Such data does not exist for molten chloride salts considered for thermal solar applications. Pure Cr, Fe, and Ni as well as FeNiCr and NiCr model alloys were exposed to KCl, MgCl2, and KCl:MgCl2 salts at temperatures of 700, 800, 850, and 900°C for times up to equilibration. The salt after exposure was then analyzed using ICP-OES to determine elemental content and solubility limits. EDS analyses was performed on the model alloys to determine dissolution profiles of each element and compared to calculations made using activity values and estimated diffusion coefficients.
