| Popis: | The technique of profile analysis of powder patterns (Rietveld's method) is used to investigate the structures of two polycrystalline phases of double oxides belonging to the Sillen phase family and having the composition 6Bi2O3 x ZnO and 5BI2O3 x 3CdO. On the basis of the results of the refinement the authors discuss the causes leading to the observed composition, which is richer in the second oxide than traditional sillenites. In these cases incorporation of atoms of the stabilizing element in the structure of el-Bi2O3 occurs both in the tetrahedral positions and in the semioctahedra of the metal atoms. |
