ELECTRODE FOR ELECTROCHEMICAL PROCESSING, METHOD FOR PREPARATION OF SAID ELECTRODE, AND PROCESS FOR PRODUCING METALLIC ALUMINIUM, AND COMPOSITE FOR PREPARATION OF ELECTRODE

摘要

A dimensionally stable combustion synthesis product of a composition containing at least 20% by weight of a particulate combustible material; at least 15% by weight of a particulate filler material capable of providing desired mechanical and electrical properties; and up to 35% by weight of a particulate inorganic binder having a melting point lower than the combustion synthesis temperature. Electrodes suitable for electrochemical processing are a preferred product form, particularly electrodes for use in the electrowinning of aluminum from its oxide.
