Abstract
The anode behaviors of new carbon electrodes impregnated with several kinds of molten metal fluorides in fluorine cell are reported. The molten fluorides are belong to IA and IIA of main group elements or IIIA of transition elements of the periodic table. The obtained results are summarized as following; 1. The carbon electrode impregnated with molten LiF was the lowest anode overvoltage among all impregnated electrodes. 2. All impregnated electrodes were able to operate at high current density such as 20 to 25A/dm 2 and anode effect was not observed in the course of electrolysis. 3. The contamination of carbon tetrafluoride in fluorine was so low as 10 to 20 ppm compared with 500 to 1000 ppm in a conventional carbon electrode.
