Abstract
Electroanalytical methods have the potential to characterize molten salt systems in situ, determine physical properties such as diffusion coefficients and standard potentials, and measure kinetic and corrosion rates. Due to experimental difficulties of working with molten salts including high temperatures and high natural convection, transport, kinetic, and corrosion rates, many precise, consistent methods have yet to be established. In this work, we describe methods to precisely calculate standard reduction potentials, characterize molten salt solutions containing multiple lanthanides by reduction potentials and metal deposition mechanisms, calculate the number of electrons exchanged in metal deposition using SWV, calculate diffusion coefficients using CV, CP, and CA, rotating electrode experiments in molten salts, perform dilatometer density experiments without the need for a calibration curve, accurately calculate the WE area exposed to molten salt using CV, calculate the mass transfer-limited current on a bare RCE, and describe the hydrodynamics around a bare RCE in molten salt.
