Abstract

Corps en carbone comportant une partie extérieure apte à être mouillée par l'aluminium et constituée d'un mélange enrichi en carbone renfermant du carbone et des particules à base de métal aptes à réagir avec l'aluminium. Les particules à base de métal sont composées de particules d'oxyde métallique et de particules d'oxyde métallique partiellement oxydées. Le métal des particules à base de métal est choisi parmi le fer, le cuivre, le cobalt, le nickel, le zinc et le manganèse. Le corps en carbone est utilisable, par exemple comme cathode, dans une cellule d'extraction électrolytique d'aluminium, ou dans un appareil de traitement de l'aluminium en fusion, et lors de sa mise en oeuvre il est mouillé par l'aluminium en fusion.
