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.
Claims18
An inert electrode suitable for use in the production of metal by the electrolytic reduction of a metal compound dissolved in a molten salt comprising a composition consisting essentially of:
- (a) an interwoven network resulting from the displacement reaction of:
- (1) a first reactant selected from the class consisting of a metal and a metal compound;
- and
- (2) a second reactant consisting of at least one metal compound,
- said first and second reactants being capable of reacting to form an interwoven network consisting essentially of:
- (1) at least one metal compound;
- and
- (2) a second material selected from the group consisting of free metal, a metal alloy, or a mixture thereof;
- and
- (b) at least one metal or metal compound which is nonreactive in said displacement reaction.
