    Graphical Abstract
    • Abstract
  • Neutron diffraction is performed on samples of the new stabilized bismuth oxide(Dy 2O 3) 0.15- x (WO 3) x (Bi 2O 3) 0 85, which possess very high oxygen ionic conductivities. One of samples( x =0.7) is annealed at 650 ℃ for 1 200 h without structural change. Results show that for DWBO samples the occupation number of 32f sites increases to a maximum and the length of 24e 32f ionic bond decreases to a minimum with the change of x. It seems to be the reason of structural stability for DWBO( x =0.7) sample.
