Structures and solid solution mechanisms of pyrochlore phases in the systems Bi2O3-ZnO-(Nb, Ta)2O5

The crystal structures of two pyrochlore phases have been determined by Rietveld refinement of combined X-ray and neutron powder diffraction data. These are stoichiometric, Bi1.5 ZnTa1.5O7 and non-stoichiometric Bi1.56Zn0.92Nb1.44O6.86. In both structures, Zn is distributed over A- and B-sites; Bi a...
