Abstract

La présente invention concerne un matériau d'électrode inerte, se présentant sous forme de poudre et comprenant des particules de taille moyenne allant de 0,1 à 100 νm, chacune constituée d'un agglomérat de grains d'une matière céramique et de grains d'un métal ou d'un alliage. Chaque grain de matière céramique comprend un nanocristal de la matière céramique et chaque grain de métal ou d'alliage comprend un nanocristal du métal ou de l'alliage. En variante, chaque particule peut être constituée d'un agglomérat de grains, chaque grain comprenant un nanocristal d'une matière céramique à une phase, d'un métal ou d'un alliage. Le matériau d'électrode sous forme de poudre selon cette invention est utilisé dans la production d'électrodes inertes présentant des propriétés de résistance au choc thermique et à la corrosion améliorées.
