A composite electrode for electrochemical processing having high temperature temperature properties, and a process for making the electrode by combustion synthesis. A composition from which the electrode is made by combustion synthesis comprises from about 40 % to about 90 % by weight of a particulate or fibrous combustible mixture which, when ignited, is capable of forming an interconnected network of a ceramic or metal-ceramic composite, and from about 10 % to about 60 % by weight of a particulate or fibrous filler material capable of providing the electrode with improved oxidation resistance and maintenance of adequate electrical conductivity at temperatures above 1000 °C. The filler material is molybdenum silicide, silicon carbide, titanium carbide, boron carbide, boron nitride, zirconium boride, cerium oxide, cerium oxyfluoride, or mixtures thereof.

Electrode composée utilisée dans un traitement électrochimique possédant des caractéristiques améliorées à haute température, et procédé de fabrication de l'électrode par synthèse de combustion. Une composition à partir de laquelle on fabrique l'électrode par synthèse de combustion comprend de 40 % environ à 90 % environ en poids d'un mélange combustible particulaire ou fibreux qui, en combustion, peut former un réseau interconnecté d'un composite céramique ou métal-céramique, et de 10 % environ à 60 % environ en poids d'une matière de charge particulaire ou fibreuse pouvant donner à l'électrode une résistance à l'oxydation améliorée et permettant à ladite électrode de conserver une conductivité électrique appropriée à des températures atteignant plus de 1000 C. La matière de charge est le siliciure de molybdène, le carbure de silicium, le carbure de titane, le carbure de bore, le nitrure de bore, le borure de zirconium, l'oxyde cérique, l'oxyfluorure cérique, ou des mélanges de ceux-ci.
