COMPOSITE ELECTRODE FOR ELECTROCHEMICAL PROCESSING AND METHOD FOR PREPARATION BY COMBUSTION SYNTHESIS WITHOUT A DIE

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.
