  • Electrolytic reduction cell
    Patent number: 4411758
    Abstract: The deterioration and distortion of the carbonaceous cathode lining of an aluminum reduction cell by freezing of molten cryolitic electrolyte in the lining and its subsequent reaction with sodium intercalated in the carbonaceous lining is substantially reduced by incorporating a composite strata comprised of at least one layer of a high temperature material which is capable of being wetted by molten glass and a layer of ground glass, e.g., cullet, between the carbonaceous lining and an insulating layer of refractory material.
