FIELD: electrolytic bath for electrolysis aluminum production, in particular cathode, casing of sidewalls. ^ SUBSTANCE: claimed material contains open-porous or gauze ceramic structure, wherein surface of said structure under using is exposed by melted aluminum and wetted therewith. Structure is made of ceramic material which is inert and resistant to melted aluminum such as alumina, and aluminum-wetted material including metal oxide and/or partially oxidized metal such as manganese, cobalt, nickel, copper or zinc, which is capable to interact with melted aluminum to produce surface layer, containing alumina, aluminum and metal, obtained from metal oxide and/or partially oxidized metal. Ceramic structure includes coating from aluminum-wetted material carried on inert and resistant material or comprises mixture of inert and resistant material and aluminum-wetted ceramic material. ^ EFFECT: construct elements of prolonged durability, produced aluminum of increased quality. ^ 34 ex, 3 dwg, 4 ex |
