摘要

Carbon cathodes are porous materials for use in aluminum reduction cells. Image analysisrnhas been applied to characterize their porous structures with respect to the penetration of cryoliticrnmelts at elevated temperatures. It was found the micro-pores orientation and connectivity showedrnstrong correlation with the amount of penetrated melts among various cathode materials. Thisrncorrelation can be explained in association with the quantitative information of the porousrnparameters and degree of graphitization for the cathodes materials. The obtained information inrnthis investigation can be useful to improve the quality of cathode products and the performancernof aluminum reduction cells.
