dc.description.abstractIn this study, (Bi2O3)(1-x-y)(Tb4O7)(x)(Gd2O3)(y) (xTbyGdSBi) ternary solid solutions were synthesized via the solidstate synthesis technique. The phase structures of electrolytes were defined by X-ray powder diffraction (XRD) and differential thermal analysis/thermal gravimetric techniques (DTA/TG). The total electrical conductivity (sigma(T)) was measured with respect to the test temperature and doping concentration by using four-point probe technique (4PPT). Measurement results showed that 8-phase was obtained in test specimens and the conductivity of the electrolytes increased with increasing test temperature and decreasing amount of Gd203. The 5Tb5GdSBi ternary system had the highest conductivity value of 3.88 x 10(-1) S cm(-1) at 850 degrees C. Compared to the literature, the results from this study are reasonably promising.
