Abstract
A metal such as aluminum is produced by electrolysis of a compound of the metal in a solvent or bath such as molten salt. Electrolysis is carried out by passing a current from an anode to a cathode between which the solvent bath is situated. The cathode is composed of a composite comprising graphite and a refractory hard metal such as titanium diboride. The properties and performance of the composite cathode are improved through careful manufacturing controls and selectivity with respect to electrode configuration and cell operating conditions.
