| Abstract Scope |
The goal of this research is to construct a basicity scale for molten halide salts to quantitively determine the effect of salt composition on structural material corrosion. Optical basicity is a quantity derived from the UV-Vis spectra of p-block transition metal ions dissolved as probes in a molten salt and is primarily dependent on the amount of free halide within the melt. The outer orbitals of the probe ions are compacted through interaction with halide anions within the salt, lowering the s-p excitation energy and thus increasing optical basicity. Preliminary studies on bismuth probe in the ZnCl2-KCl system have been conducted and produced results adjacent to the AlCl3-KCl system that has historically been studied in the context of optical basicity. Further investigation of this system and other chloride/fluoride salts as well as studies on Tl+ and Pb2+ as probe ions are being performed to determine the best optical basicity probe. |
