The work was devoted primarily to studying the anodic polarization of Monel in anhydrous hydrogen fluoride AHF and to the electrolysis of ammonium fluoride NH4F in AHF using Monel as the working electrode. Conductance studies were also performed to determine the rate of contamination of the AHF as it was held in the sealed cells. Determinations of the effects of electrolysis and additions of water and NH4F on the conductivity of HF were also made. Pyrolytic carbon was investigated as a possible electrode material. The carbon was mounted in Kel-F to expose only a single crystal plane, and, although it resisted attack by AHF, it disintegrated when fluorine was evolved anodically. Results to date indicate that fluorination during the electrolysis of NH4F in AHF proceeds by chemical rather than by an electrochemical mechanism.
