  • Composition for making wettable cathode in aluminum smelting
    Patent number: 11041250
    Abstract: Compositions for making wettable cathodes to be used in aluminum electrolysis cells are disclosed. The compositions generally include titanium diboride (TiB2) and metal additives. The amount of selected metal additives may result in production of electrodes having a tailored density and/or porosity. The electrodes may be durable and used in aluminum electrolysis cells.
    Type: Grant
    Filed: September 24, 2018
    Date of Patent: June 22, 2021
    Assignee: ALCOA USA CORP.
