摘要：

The ternary oxides in the compositional range from Bi//2O//3 to BiVO//4 have been investigated using electron diffraction and high-resolution electron microscopy. With small concentrations of vanadium, a solid solution based on gamma -Bi//2O//3 was found to occur, but at greater vanadium contents, a 3 multiplied by 3 multiplied by 3 superstructure derived from fluorite was first observed, followed by a family of triclinic superstructures containing fluorite-like and pyrochlore-like basic units. The details of these structures are discussed.
