Abstract

En celle for elektrolytisk ekstraksjon av aluminium har én eller flere anoder (10) som vender mot minst én katode (20). Denne katoden omfatter: et katodelegeme (25) fremstilt hovedsakelig av minst ett hardmetall valgt fra wolfram og molybden, og en karbidoverflate (26,27) av dette hardmetallet som er integrert med legemet eller som er dannet av et lag bundet til legemet. Karbidoverflaten danner en katodisk funksjonell overflate på hvilken aluminium (9) er fremstilt i løpet av anvendelse, eller hvor karbidoverflaten danner en forankringsoverflate for et aluminiumsvætende, keramisk lag (28,29) på hvilken aluminium er fremstilt i løpet av anvendelse.
