ABSTRACT:
This invention relates to electrolytic reduction cells for aluminum production wherein tiles have been placed upon the cathode surfaces to improve the cell operation. These tiles have aluminum-wettable surfaces, which reduce electrical losses and increase cathode life. The tiles are produced from a mixture of refractory hard metal (RHM), a thermosetting resin, carbonaceous fillers and carbonaceous additives. The tiles are physically formed, polymerized and/or cross linked, and carbonized to form a tile which can be inserted into a cell. The tile may have the RHM homogeneously dispersed throughout the tile structure, or it may have the RHM concentrated in layered form.
