Development of an inert anode for electrowinning in calcium chloride-calcium oxide melts
Reports a stable inert anode material that can be used in oxide melts. The anodic reaction is then evolution of oxygen rather than the carbon dioxide obtained using conventional carbon anodes. Opens the opportunity for greener processing where a metal oxide is simply reduced to the metal and oxygen using the FFC Cambridge Process (commercialized by Cambridge University spin out, Metalysis Ltd: www.metalysis.com). The inert anode could be used in high-temperature metal-air batteries or even to reduce the lunar regolith to provide oxygen on the moon [follow-up work from Fray’s group: Planetary and Space Science 74(2012)49-56 2012].
