Anex situcharacterization study has been performed on rutile passivation layers on inert anodes used for molten salt electrochemical studies. Rutile layer thicknesses were estimated using a number ofex situmethods, including laboratory and synchrotron X-ray diffraction and optical microscopy. The only phases in the anode detected by diffraction were the Magnéli phases (TinO2n−1,n= 5–6) of the unreacted anode and rutile (TiO2), which forms on electrolysis. These measurements validate a previously developedin situenergy-dispersive X-ray diffraction analysis technique [Scarlett, Madsen, Evans, Coelho, McGregor, Rowles, Lanyon & Urban (2009).J. Appl. Cryst.42, 502–512].
