FREMGANGSMAATE VED FREMSTILLING AV EN KOMPOSITT AV KERAMISK MATERIALE OG METALL (KERMET)

摘要

A cermet is produced by providing a bulk reaction mixture of particulate reactants which react to produce a self-sustaining ceramic body, and carrying out the reaction with the bulk reaction mixture in contact with molten metal which moderates the reaction and infiltrates the resulting ceramic body. The method is particularly applicable for boride-based ceramics infiltrated with aluminum, suitable as components of electrolytic cells for the production of aluminum by molten salt electrolysis.
