Abstract
A cathodic element for a Hall-Heroult aluminum reduction cell is formed from a refractory hard metal, preferably TiB.sub.2, in a generally mushroom-shaped configuration. The element is economical of raw materials and has improved thermal endurance when compared to a right cylinder or other element of uniform cross-section.
