Abstract
An improved cell is disclosed for producing metal by electrolytic reduction of a metal halide dissolved in at least one molten halide of higher electrodecomposition potential than the metal halide. The cell includes a plurality of cell elements, including an inner refractory lining and a plurality of carbonaceous elements. Included among the carbonaceous elements are carbonaceous lining elements located inside of and abutting a portion of the inner refractory lining and carbonaceous electrode elements abutting the inner refractory lining. In a preferred embodiment of the invention, some carbonaceous lining elements abut other carbonaceous lining elements, and some carbonaceous electrode elements abut other carbonaceous electrode elements. The improved cell also includes carbon felt gaskets located between at least some of the abutting elements for sealing of the joints of abutment in order to minimize the effects of physical shifts in the carbonaceous elements.
