Abstract
A cermet is produced by providing a bulk reaction mixture of particulate reactants plus elemental metal, which reaction mixture is in admixture with a ceramic diluent that is the same as ceramic material formed during sintering of the reaction mixture. Sintering produces a boride-oxide ceramic with the oxide being a metal oxide of the elemental metal. However, the elemental metal is present in the reaction mixture in substantial excess over that amount stoichiometrically required. Sintering is conducted under inert atmosphere, generally after pressing. The invention is particularly directed to boride-based ceramics containing aluminum, which materials are suitable as components of electrolytic cells for the production of aluminum by molten salt electrolysis.
