An electroanalytial study on the anode process of carbon electrode in LiF-NaF-KF melt was carried out by cyclic voltammetry (CV), chronoamperometry (CA). and gas chromatography. At the potentials higher than 3.7 V versus K+/K the anode effect appeared and generation of perfluorocarbons (PFCs) such as CF4 and C2F6 was observed from the same potential. At 1223 K. the current stayed at very lower level over the range of high potentials (>3.5 V), and only small amount of PFCs was detected, while at lower temperatures, large value of PFCs generation was observed from the potential higher than 7.0 V.
