Abstract

Komponenter for elektrolytiske celler for produksjon av aluminium, spesielt ved elektrolyse av alumina i en smeltet luoridelektrolytt, laget av karbon eller annet mikroporøst materiale som holder seg stabilt eller som kan forbrukes under cellearbeidsbetingelsene, kondisjoneres for bedre å motstå cellearbeidsbetingelsene ved å impregnere disse med kolloidalt ceriumoksid, ceriumacetat, silika, alumina, litiumoksid, yttriumoksid, thoriumoksid, zirkoniumdioksid, magnesiumoksid eller monoaluminiumfosfat inneholdende ioniske arter av natrium, litium, kalium, aluminium, kalsium eller ammonium, etterfulgt av tørking og varmebehandling.
