ABSTRACT:
An improved alumina reduction cell is described in which the carbonaceous cathode includes refractory hard metal tiles forming the surface in contact with molten aluminum formed in the cell and intermediate tiles separating the refractory hard metal tiles from the carbonaceous cathode to prevent reaction between refractory hard metal tiles and the carbonaceous cathode in the presence of the molten aluminum.
