Abstract

Den foreliggende oppfinnelse tilveiebringer en metode for fremstiUing av en karbonelektrode, egnet for bruk som en anode i en aluminiumreduksjonsceUe, omfattende sammenblanding av et aggregat, omfattende en blanding av partikkelformet haglkoks ("shot coke"), og et annet karbonholdig materiale enn nevnte haglkoks med kulltjærebek eller petroleumsbek eller en kombinasjon av disse bek, ved en forhøyet temperatur for å danne en pasta hvori nevnte aggregat omfatter en kombinasjon av grove, middels og fine partikler og nevnte partikkelformede haglkoks kan omfatte en hovedmengde av de fine partikler, og den nevnte pasta omfatter fra omtrent 80 til omtrent 90 vekt% av det nevnte aggregat og fra omtrent 10 til 20 vekt% av det nevnte bek; den nevnte pasta tildannes til et fast legeme; og det faste legemet bakes ved en forhøyet temperatur for å danne nevnte karbonelekfrode.
