Rhenium Electrodeposition and Its Electrochemical Behavior in Molten KF-KBF-BO-KReO.

The electrochemical behavior of rhenium ions in the molten KF-KBF-BO salt was systematically studied, and pure metallic rhenium was obtained at the cathode. The processes of rhenium ions reduction and diffusion in molten KF-KBF-BO were determined using cyclic voltammetry, stationary galvanostatic and polarization curves analyses. The values of diffusion coefficients were 3.
