“…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.…”
