FIELD: technological processes.SUBSTANCE: invention relates to versions of an electrochemical method of forming crystals of tungsten oxide bronze from nanowhiskers. One of the versions involves electrolysis of a poly-tungsten melt using a platinum anode, in which electrodeposition is carried out at 700 °C in pulse potentiostatic mode from melt containing 25 mol% KWO, 25 mol% NaWOand 50 mol% WO, with a single rectangular-shaped voltage pulse of -855 mV and duration of 1 s, wherein the copper cathode used is copper foil.EFFECT: high-temperature electrochemical method enables to form crystals of tungsten oxide bronze from nanowhiskers, which have length to diameter ratio >1,000.6 cl, 6 dwg |
