Aluminum Production Paths in the New …

Titanium diboride was first promoted as a useful cathode material for aluminum smelting cells in the 1950s. 7 It has an exceedingly low solubility product in the metal, while the metal contamination is sometimes considered an advantage because of the refining processes to which the metal is subject. Titanium diboride is wetted by aluminum, thus potentially lowering interfacial voltage drops ...
