Abstract (en)
[origin: WO8702069A1] Alumina oxide and other non-metallic compounds, such as lithium oxide, are removed from molten aluminium-lithium alloys by filtration through a porous ceramic body comprising silicon carbide. The porous ceramic body may be, for example, a honeycomb type of structure or a foam having interconnecting pores.
Abstract (fr)
L'oxyde d'alumine et d'autres composés non métalliques, tels que l'oxyde de lithium, sont extraits d'alliages d'aluminium-lithium en fusion par filtrage à travers un corps céramique poreux comprenant du carbure de silicium. Le corps céramique poreux peut être, par exemple, une structure en nid-d'abeilles ou une mousse possédant des pores communiquants.
