Electrolysis of the melts of NH4F·2HF with and without metal fluorides such as LiF, NaF, KF, CsF, MgF2, and AlF3 was conducted with a nickel anode. The mixed gas composed of NF3 and N2 with a small amount of N2F4, N2F2, N2O, and O2 was liberated at the anode by electrolysis at 25 mA/cm2 and at 120°. The addition of LiF into the melt was most effective for increasing the NF3 current efficiency and for minimizing the consumption of nickel anode. In contrast, KF in the melt decreased the current efficiency for NF3 and other constituents in the anode gas as well as hydrogen generated at the cathode. It also stimulated the consumption of Ni anode. The concentration of nickel ion in the molten KF-NH4F-HF system was low compared with that in the melts of NH4F·2HF with and without alkali metal fluorides such as LiF and CsF because KNiF3 was deposited on the cathode and the cell bottom. The SEM observation and the XPS and XRD analyses revealed that the oxidized layer formed on nickel in molten NH4F·2HF with and without LiF, CsF, and 0.3 mol% NaF was composed of NiF2 with a small amount of Ni oxides of divalent and trivalent states and highly oxidized nickel fluorides. The surface layer formed on nickel in molten NH4F·2HF with 6.7 mol% NaF was mainly composed of NiF2 and NaNiF3. On the other hand, the oxidized layer in the melt containing KF was composed of only KNiF3, and was very brittle. Therefore, it is concluded that KF is detrimental to the nickel anode, depending on the composition of molten fluoride.
