KOMPONENTER FOR ALUMINIUMPRODUKSJONSCELLER

摘要

An electrolytic aluminum-production cell component, comprising a preformed matrix based on at least one material from the group alumina, aluminum oxynitride, SiAION, boron nitride, silicon carbide, silicon nitride, aluminum boride and carbides, carbonitrides, boronitrides and borcarbides of metals from Group IVb (titanium, zirconium and hafnium) Group Vb (vanadium, niobium and tantalum) and Group VIb (chromium, molzbdenum and tungsten) having voids extending throughout its structure, the voids in the preformed matrix structure being filled or substantially filled with aluminum in intimate contact with the matrix.
