In an electrolytic cell having a floor and a boundary for the floor, the cell having a short side and a long side, the improvement including greater compressibility in the boundary on the short side of the cell, as compared to the long side of the cell, in an amount effective for accommodating longitudinally directed expansion of the floor, to counteract longitudinal cracking of the floor.

Electrolytic cell

An electrode assembly comprising an electrically conductive ceramic electrode body having an opening therein and a metal stub retained in the opening with at least a surface of the stub in intimate contact with a surface of the body and the stub adapted with a spring to flex and prevent damage to the body from expansion of the stub when subjected to a temperature differential.

Metal spring stub and ceramic body electrode assembly

An electrically conductive ceramic electrode body having an opening therein is threadably engaged with a metal stub having at least a slot therein to provide space for expansion of the stub without damage to the electrode body.
