Abstract
Tetrafluoroborate melts have been shown to be viable electrolytes for the electrochemical production of fluorine from dissolved . The anode reaction at pyrolytic graphite electrodes apparently involves the oxidation of and/or F− to yield and . may be used to trap ; the resulting may be reused in the bath. Observed anode current efficiencies are generally on the order of 50–60% at an optimum anode current density of 40 mA/cm2. The cathode reaction at tin and/or zinc cathodes involves the reduction of Ca2+ to the metal along with the reduction of alkali metal ions to the respective metals. The presence of zinc in the cathode pool appears to favor the deposition of calcium over that of alkali metals.
