| Abstract Scope |
Carbon cathodes are porous materials for use in aluminum reduction cells. Image analysis has been applied to characterize their porous structures with respect to the penetration of cryolitic melts at elevated temperatures. It was found the micro-pores orientation and connectivity showed strong correlation with the amount of penetrated melts among various cathode materials. This correlation can be explained in association with the quantitative information of the porous parameters and degree of graphitization for the cathodes materials. The obtained information in this investigation can be useful to improve the quality of cathode products and the performance of aluminum reduction cells. |
