Definitions

  • the invention relates to a ceramic material which can be utilised for the manufacture of aluminium-wettable and aluminium-wetted ceramic components, in particular for use in aluminium production, for example as cathodes, sidewalls and other cell components which during use are exposed to molten aluminium, electrolyte and/or corrosive gases .
  • the openly porous ceramic structure may be formed on a reinforcing metal skeleton, in particular a metal mat.
  • Suitable metals for such a skeleton include iron and iron alloys and other metals which are mechanically resistant at elevated temperature.
  • the resulting structure was aluminium-wettable and suitable to be wetted by aluminium before use or in- itu when used for example as a cathode.
  • the aluminium-wetted porous structure can be used as cathodic material like in Example 3.

Abstract

L'invention concerne un matériau, utilisé par exemple comme composant mouillable par l'aluminium (21, 21', 41, 41', 51), en particulier d'une cellule d'extraction électrolytique d'aluminium (60), et qui comporte une structure en céramique réticulée ou à porosité ouverte dont la surface est exposée, lors de l'utilisation, à de l'aluminium en fusion et est mouillée par celui-ci. La structure est composée d'un matériau céramique inerte et résistant à l'aluminium en fusion, comme l'alumine, et d'un matériau mouillable par l'aluminium contenant un oxyde métallique et/ou un métal partiellement oxydé _ ce métal étant plus particulièrement du manganèse, du fer, du cobalt, du nickel, du cuivre ou du zinc _ qui réagit/réagissent avec l'aluminium en fusion pour former une couche superficielle contenant de l'alumine, de l'aluminium et du métal issu de l'oxyde métallique et/ou du métal partiellement oxydé. La structure en céramique comprend un revêtement constitué du matériau mouillable par l'aluminium et recouvrant le matériau céramique inerte et résistant ou se compose d'un mélange du matériau inerte et résistant et du matériau céramique mouillable par l'aluminium. Le composant mouillé par l'aluminium peut être utilisé comme cathode (21, 21'), paroi latérale (41, 41') ou un autre composant (51) qui, lors de son l'utilisation, est exposé à de l'aluminium en fusion (60) et/ou à un électrolyte (5) ou un autre milieu oxydant et/ou corrosif à température élevée.
