摘要：
The series of Gd-Bi-Ce-O solid solutions were synthesized by co-precipitation method with sonication. These mesoporous nanocrystalline powders with the size of about 15 nm were used as precursors to ceramics formation, sintered at 1000 degrees C in air, for the application of materials as an electrolyte for IT-SOFC. The electrical conductivity of these materials was measured by AC impedance spectroscopy in the temperature range of 450-750 degrees C in air. It was showed that Gd0.05Bi0.15Ce0.8O2 ceramics, prepared through acetylacetonate complex, is the perspective system for this goal and has the conductivity of 5.10 (3) S/cm at 600 degrees C in air.
