Abstract

The cubic sodium tungsten bronzes, Na_xWO₃ (x = 0.854 and 0.814) were prepared by rare earths gaseous permeation method. Structural analysis was carried out by Rietveld method from powder X-ray diffraction data. The X-ray diffraction profile calculated with cubic P32 models are in good agreement with the observed X-ray diffraction patterns. There is only a little difference in W-0 bond and Na-0 bond between Na_0.854WO₃ and Na_0.814 WO₃. Conductivity measurements indicate that Na_xWO₃ show anomalous semiconducting behavior and percolation model was used to interpret it.
