| Abstract Scope |
Despite the breadth of molten salts' potential industrial applications such as in thermal energy storage, solar power, nuclear power and pyroprocessing, the incremental impact of salt basicity and halide potential on the corrosivity of molten halide to structural materials is still not well understood. This gap in knowledge hinders development of sufficiently robust structural materials to support advancement of molten salt technologies. With the goal of understanding the fundamental properties of the molten halide solvent environment, we demonstrate a time-series parametric corrosion study in which Ni-20Cr samples each of surface area ~0.9cm2 were exposed to 16 unique compositions of salt each ~0.2g: in the 4x4 experiment matrix, salt basicity was varied by KCl composition and chlorine potential was independently varied by EuCl3 concentration. Corrosion salts were analyzed for corrosion product concentration, oxidation state and ligand coordination. |
