Abstract

Disclosed is a method for producing graphitized cathode blocks. A carbonized cathode block is used in a longitudinal graphitization method, the cross section of said block being larger at the ends of the block than in the middle thereof. At least part of the graphitized material is removed from the ends upon graphitization. Also disclosed are cathode blocks produced according to the inventive method and the use thereof for the electrolytic production of aluminum.
