The ionic conductivity and local environment of cations in Bi9ReO17

Synthesis, structure, characterization and photocatalytic activity of Bi2Zr2O7 under solar radiation

“…Therefore, efforts have been made to stabilize the d-Bi 2 O 3 form at room temperature via substitutions at the Bi site. [5][6][7][8][9] Cation size plays an important role in stabilizing the FCC phase. It was found that smaller rare earth ions were more effective in stabilising the d-phase at room temperature.…”

INFLUENCE OF SYNTHESIS PROCESS ON THE COLOUR PROPERTIES OF MIXED OXIDE PIGMENT Bi1.5Zn0.5Ce₂O₇

“…It is also possible to use a combination of oxides, so-called double doping, to obtain the δ fluorite type phase. Fluorite-type δ-phase materials display very high oxide ion conductivity which is attributed to the highly polarizable Bi 3+ cations and the highly disordered structure of the sublattice [9][10][11][12].…”
