A static corrosion experiment at UW-Madison aims to demonstrate the ability to mitigate corrosion of structural materials at 700?C by controlling the FLiBe salt redox condition. The utility of an electrochemical cell potential called the FLiBe salt redox potential is investigated as a metric for predicting the corrosive potential of FLiBe salt. In general, a salt which possesses a redox potential that is small in magnitude is considered less corrosive, more reducing, than a salt with a larger, more oxidizing, redox potential. The magnitude of the cell potential, measured between a molybdenum electrode and a dynamic beryllium reference electrode (DBRE), is correlated with the introduction of common FLiBe salt impurities, such as chromium, iron and nickel fluorides. Corrosion samples were exposed to FLiBe with varying redox conditions: as received purified FLiBe and FLiBe which has been chemically reduced with beryllium metal. The salts were characterized using the FLiBe salt redox potential and spectroscopic analytical chemistry to elucidate the importance of controlling the salt redox condition during reactor operation.
