Method for preparing a composite carbon material with a view to the use thereof for manufacturing carbon blocks

摘要

The invention relates to a method for preparing a composite carbon material. Said method includes at least the following steps: a) preparing a mixture containing at least carbon raw materials, a solvent, and lignin; b) gellifying the mixture resulting from Step a) until a composite carbon material paste is obtained; and c) shaping the composite carbon material paste resulting from Step b) so as to give it a desired shape. The composite carbon material is intended to be used for manufacturing carbon blocks that are used as electrodes in aluminum electrolysis cells or in steel mill furnaces, or more generally as refractory materials.
