Abstract
En komponent for en aluminiumproduksjonscelle, spesielt en katode eller en cellefóring for en elektrolysecelle for produksjon av aluminium ved elektrolyse av alumina i kryolitt, med et ildfast belegg som lar seg fukte av aluminium, på et varmestabilt brent karbonholdig legeme er fremstilt fra en delprodusert cellekomponent som er en sjiktkompositt av to forløpere. Et forløperlag for det ildfaste belegg som lar seg fukte av aluminium, inneholder minst ett ildfast materiale i partikkelform som lar seg fukte av aluminium, eller en partikkelformig mikropyretisk reaksjonsblanding som ved antennelse reagerer under dannelse av minst ett ildfast materiale som lar seg fukte av aluminium, eller en blanding derav, og ikke-karbonfyllstoffer og bindemidler. En ikke brent eller delvis brent forløper for det varmestabile karbonholdige legeme omfatter partikkelformig karbon kompaktert med et varmeomvandlingsbart bindemiddel som når det utsettes for varmebehandling, binder det partikkelformige karbon under dannelse av det varmestabile karbonholdige legeme for den fullproduserte cellekomponent. Denne sjiktkompositt kan omvandles til den fullproduserte cellekomponent ved varmebehandling for å danne det ildfaste belegg som lar seg fukte av aluminium, og samtidig binde og varmestabilisere det karbonholdige legeme.
