OXIDE MATERIAL FOR INFLAMMABLE ANODES OF ALUMINUM CELLS (VARIANTS) Russian patent published in 2007 - IPC C25C3/12 C04B35/00 B22F3/16 

FIELD: non-ferrous metallurgy, possibly manufacture of inert anodes for producing metals by electrolysis of melts, namely electrolytic production of aluminum in cryolite - alumina melts.

SUBSTANCE: oxide material for making inflammable anodes of aluminum cells represents high-substitution complex oxides on base of tin dioxide of rutile structure type of formula Me³ _x + Me⁵ _x + Sn_2-2x O₄ or cermets on their base having low solubility in cryolite - alumina melt, high electrical conductivity and improved resistance against gas corrosion and against contact reduction by metals.

EFFECT: possibility for producing increased-purity aluminum at low energy losses.
