FFC Cambridge process
The FFC Cambridge Process is an electrochemical method in which ''solid'' metal compounds, particularly oxides, are cathodically reduced to the respective metals or alloys in molten salts. It is thought that this process will eventually be capable of producing metals or alloys more efficiently than by current conventional processes, such as titanium by the Kroll process. Producing tantalum can also make use of this process.
==History==
The FFC Cambridge process was developed by George Chen, Derek Fray and Tom Farthing between 1996 and 1997 at the University of Cambridge. (The name FFC derives from the first letters of their last names.) They reduced oxide scales on titanium foils, as well as small pellets of titanium dioxide powder, to the metal by molten salt electrochemistry. The technology has since been commercialised in the form of an intellectual property company known as Metalysis, which is based in Sheffield, UK.〔(Metalysis Official Website )〕 A similar process was patented in 1904 as German patent 150557.〔(DRP 150557 "Verfahren der Gewinnung von Titan aus seinen Sauerstoffverbindungen auf elektrolytischem Wege" ). dpma.de〕〔Rideal, Eric Keightley (1919) (''Industrial Electrometallurgy, Including Electrolytic and Electrothermal Processes'' ). D. Van Nostrand co. p. 137〕
