Abstract
Intergrowth tungsten bronzes of stoichiometry Bi//xWO//3 (x approx. 0. 1-0. 2) have been examined by 500kV high-resolution electron microscopy (HREM) before and after annealing in vacuo at 950 degree C. In untreated samples, the ITB structure has been directly confirmed. After heat-treatment, the material was observed to decompose to a disordered Aurivillius phase, with some reduction of the remaining WO//3 matrix. The conversion clearly took place in a topotactical manner and both lamellar and equidimensional nuclei developed.
