Abstract

The oxidation of bismuth-tungsten bronzes at 600 and 950°C has been studied using high-resolution electron microscopy at 200 and 500 kV. At the lower temperature, a topotactic transformation to lamellae of Bi₂WO₆ in a WO₃ matrix was observed but at higher temperature larger crystals were produced, primarily of Bi₂W₂O₉ but with some disordered intergrowths.
