Abstract: Single crystals of ternary sodium tungsten bronzes have been prepared by the electrolysis of molten Na2WO4-WO3 system. X-ray powder diffraction and energy dispersive spectroscopy results reveal that the obtained samples are of cubic phase with empirical formula of Na0.54WO3. Electrical resistivity measurement indicates a metallic conducting behavior without any anomaly from 5-300 K.
