Material for structural components of an electrowinning cell for production of metal

Abstract: the formula A′1−tA″tO, in which A′ and A″ are divalent elements from the group Co, Ni, or Zn. O is the element oxygen. 0≦t<1. the formula A′1−sA″sTiO3, in which A′ and A″ are divalent elements from the group Co, Ni, or Zn. O is the element oxygen. 0≦s<1  or the formula (A′1−uA″u)x(B′1−vB″v)y(C′1−wC″w)zO4, in which A′ and A″ are divalent elements from the group Co, Ni, or Zn, B′ and B″ are trivalent elements from the group Al, Cr, Mn, or Fe, and C′ and C″ are the tetravalent elements Ti or Sn. O is the element oxygen. 0≦u<1, 0≦v<1, 0≦w<1 1≦x≦2, 0≦y≦2 and 0≦z≦1, x+y+z=3 and 2x+3y+4z=8,  or A material suitable for use for structural components in a cell for the electrolytic reduction of alumina to aluminium metal defined either by: (end of abstract)
