Abstract

L'invention concerne un procédé pour produire un bloc cathodique, qui présente les étapes suivantes: fournir des matériaux de base comprenant du coke et une poudre de matériau dur, par exemple TiB2, ainsi qu'éventuellement un matériau carboné; mélanger les matériaux de base; mouler un bloc cathodique; carboniser et graphiter, puis refroidir. Selon l'invention, l'étape de graphitation est effectuée à des températures comprises entre 2.300 et 3.000 °C, en particulier entre 2.400 et 2.900 °C.
