    Abstract: The present invention provides a ceramic to ceramic joint and methods for making such a joint. Generally, the joint includes a first (15) ceramic part and a second (20) ceramic part, wherein the first (15) and second (20) ceramic parts each include a ceramic-carbide or a ceramic-nitride material. In some cases, an aluminum-initiated joint region joins the first (15) and second (20) ceramic parts. This joint region typically includes chemical species from the first (15) and second (20) ceramic parts that have diffused into the joint region. Additionally, the first (15) and second (20) ceramic parts each typically include a joint diffusion zone that is disposed adjacent to the joint region and which includes aluminum species from the joint region that have diffused into the joint diffusion zone. Other implementations are also described.

    Abstract: Composite materials comprising titanium diboride and boron nitride that are used to line electrolytic aluminum production cells (10) are disclosed. The composite materials may be used to line the side walls (14, 16) and/or bottom wall (12) of the cell (10). 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 (10) in which the liner plate (12, 14, 16) is installed. The titanium diboride/boron nitride composite materials exhibit desirable aluminum wetting behavior, and are capable of withstanding exposure to molten cryolite (20), molten aluminum (22) and oxygen at elevated temperatures during operation of the electrolytic aluminum production cells (10).
