摘要： An adherent protective coating of a refractory material is produced on the surface of carbonaceous, refractory, ceramic, metallic or other materials serving as components of electrolytic cells operating at high temperature, by applying to such surfaces a well chosen micropyretic reaction layer from a slurry, which when dried is ignited to initiate a self-sustaining micropyretic reaction, along a combustion front, to produce condensed matter forming such refractory protective adherent coating. The slurry is preferably applied in several layers, the first layer(s) to facilitate adherence and the last layer(s) to provide protection and may contain some preformed non-reactant materials. The electrolytic cells whose components require such coatings are especially those operating at high temperature with a molten salt electrolyte, particularly those for the production of metals, aluminum being the most important. For these cells the invention provides an aluminum-wettable, adherent, refractory, protective coating for the cell-bottom carbon cathode, containing RHM material such as titanium diboride, as well as other refractory protective coatings for cell wall lining and for other cell components. Novel cell designs for the utilization of the different coatings are also provided.

摘要： The amount of electrically conductive material in the bottom floor lining of a conventional aluminum reduction cell is reduced by using a non-conductive lining material in its place. The non-conductive material separates the remaining electrically conductive regions from the sidewall linings of the cell and preferably confines the electrically conductive material to the "anode shadow" region of the cell floor. In another embodiment joints between the conductive and non-conductive regions are positioned such that they are covered by cell freeze (solid electrolyte) during operation of the cell. This prevents liquid cell contents penetrating the joint and adversely affecting the cell lining, thus shortening the life of the cell. The non-conductive material preferably comprises a particulate alumina mixture made up of large shapes which firmly compact together and smaller particles which fill the remaining voids. Optionally, the mixture may be bonded together with amorphous alumina, in which case the mixture can also be used for cell wall linings. The linings can be used in reduction cells of conventional design and reduces undesirable magnetohydrodynamic effects as well as pollution hazards caused by conventional carbonaceous cell linings.
