<p>A ceramic/metal composite material comprising cerium/aluminum mixed oxides as the ceramic phase (6) and an alloy or intermetallic compound of cerium and at least one of aluminum, nickel, iron and cobalt as the metal phase (7). The ceramic phase may comprise interengaged crystal lattices of ceria and alumina. The material may be a self-sustaining body which may be used as substrate for a dimensionally stable anode in moltensalt aluminum electrowinning cells, coated with a protective layer of cerium oxyfluoride (10) in situ during electrolysis in molten cryolite (9) containing cerium ions.</p> |
