Abstract
The carbon electrodes for fluorine electrolysis were prepared from petroleum cokes containing coal tar pitch as binder and the effects of binder contents on electrode properties were investigated. The evaluations were performed by cyclic voltammogram in the 0.5 M $K_2SO_4$ solution with 1 mM $[Fe$(CN)_6$]^{3-}$/$[Fe$(CN)_6$]^{4-}$redox couple, mechanical strength, and electrochemical behaviour in molten $KF{\cdot}2HF$ electrolyte. It was revealed that the carbon anode formed with 40wt% of coal tar pitch as binder has a better electrode properties compared to those of the other carbon anode, which led to the increase in the effective internal surface area due to proper size and distribution of pores on carbon anode.????????????5???K?޿
