Abstract
The invention relates to a cathode block for an aluminum electrolytic cell composed, at least in some sections, of a material that can be obtained by burning a mixture, which mixture contains at least one material containing carbon having a degree of graphitization calculated in accordance with Maire and Mehring from the mean layer distance c/2 after a heat treatment at 2,800 °C of at most 0.50 and at least one nonoxide ceramic.
