Title: Composition suitable for inert electrode

Abstract

An inert electrode composition suitable for use in the production of metal by the electrolytic reduction of a metal compound dissolved in a molten salt is disclosed. The composition is formulated from a body containing metals and metal compounds designed to undergo displacement reaction upon sintering to form an interwoven network. The body also contains at least one non-reactive material, e.g., metal compound or metal. The interwoven network contains at least a metal compound and a second material, both resulting from the displacement reaction, the second material selected from the group consisting of free metal and a metal alloy or a mixture thereof.
