In this study, Sb₂O₃ (Sb₂O₅) and Ta₂O₅ are used as co-dopants with TeO₂ to stabilize the delta phase of bismuth oxide (δ -Bi₂O₃). Some compositions with formula (1-x) BiO_{1.5}-(x/4) Sb₂Te₂O₉ and (1-x) BiO_{1.5}-(x/4) Ta₂Te₂O₉ (x=0.1, 0.2, 0.3, 0.6, and 0.9) have been synthesized by solid state reaction at 850°C and characterized by powder X-ray diffraction. The Bi_{0.9}Sb_{0.05}Te_{0.05}O_{1.575}, Bi_{0.9}Ta_{0.05}Te_{0.05}O_{1.575} and Bi_{0.8}Ta_{0.1}Te_{0.1}O_{1.65} retain a cubic fluorite structure of δ -Bi₂O₃ phase. The electric properties were studied by impedance spectroscopy. All samples were evaluated by calculating conductivities and activation energies. Various impedance model including constant phase element and the Warburg impedances have been used to interpret the Nyquist representations of electrical analyses.
