Electrochemical oxidation of binary copper-nickel alloys in cryolite melts [PDF]

open access: yes, 2007
Anodic oxidation of copper, nickel and two copper-nickel alloys was studied in cryolite melts at 1000°C. In an oxide-free melt, anodic dissolution of each material was observed, and the dissolution potential increases with the content of copper.
