Abstract (en)
[origin: WO8906289A1] An improved electrolytic cell and process are provided wherein metals and metal alloys are formed from oxides or nitrides in a molten salt (13), without the evolution of halogen or halogen compounds, with less corrosion and reduced power consumption by the use of an electrode (11), having an extended or substantially increased surface area effective for the evolution of oxygen and carbon oxide, and a molten salt electrolyte effective at low temperature.
