Abstract

Procédé de préparation d'un élément moulé en argent et au moins deux oxydes de métaux non nobles pour contact électrique. Le procédé consiste à transformer la masse fondue d'argent et d'au moins deux métaux non nobles choisis parmi Cd, Bi et/ou Pb, avec une teneur en métaux non nobles telle que l'élément moulé final renferme moins de 20 % en volume des oxydes de ces métaux, en une poudre alliée, par atomisation sous pression en utilisant l'eau comme agent support et à transformer ensuite ladite poudre alliée en l'élément moulé recherché par oxydation interne, compression, frittage et repassage à la presse.
