  • Publication number: 20110114479
    Abstract: Composite materials comprising titanium diboride and boron nitride that are used to line electrolytic aluminum production cells are disclosed. The composite materials may be used to line the side walls and/or bottom wall of the cell. The ratio of titanium diboride to boron nitride may be controlled in order to provide the desired level of electrical conductivity depending upon the particular region of the cell in which the liner plate is installed. The titanium diboride/boron nitride composite materials exhibit desirable aluminum wetting behavior, and are capable of withstanding exposure to molten cryolite, molten aluminum and oxygen at elevated temperatures during operation of the electrolytic aluminum production cells.
