INERT ANODES FOR ALUMINUM ELECTROLYSIS AND METHOD OF PRODUCTION THEREOF

摘要

An inert anode for Al electrolysis, made of Cu-Ni-Fe-0 based materials, comprising Fe in a range between about 10 and 20 % by weight, Cu in a range between about 60 and about 80% by weight, Ni in a range between about 20 and about 30% by weight, and oxygen in a range between about 1 and about 3% by weight, and a method for producing the anode, comprising mechanically alloying metallic elements; oxygen doping; and consolidation.
