Electrolytic growth of vanadium dioxide in an oxide electrolyte crucible

Preparation of Vanadium‐Tungsten‐Oxide Wadsley‐Roth Phases by Electrolytic Reduction of Molten Salts

“…The ratio of tungsten to vanadium in the melt is found to control the phase of the product formed. I n the absence of WO3, the electrolysis of molten V205 yields elongated prismatic crystals of VOz (6,7). At the lowest concentration of WO3 examined in this study (1W: 25V), a mixture of V~WO7.5 and V2.4W0.607 is formed during the electrolysis.…”
