Gadolinium doped ceria solid electrolyte prepared by different methods under the same sintering profile were examined in terms of microstructure and ionic conduction performance. The GDC powders were synthesized by a modified sol gel combustion synthesis and hydrothermal treatment. X-ray diffraction (XRD) and transmission electron microscopy (TEM) results revealed that the crystal structures of the powders synthesized by the two methods developed differently. After sintering, they showed different grain morphologies. Consequently, the electrolyte prepared from the two kinds of powders demonstrated different microstructures and different ionic conductivity. The electrolyte synthesized by sol gel methodology showed the highest ionic conductivity.

Abstract

Gadolinium doped ceria solid electrolyte prepared by different methods under the same sintering profile were examined in terms of microstructure and ionic conduction performance. The GDC powders were synthesized by a modified sol gel combustion synthesis and hydrothermal treatment. X-ray diffraction (XRD) and transmission electron microscopy (TEM) results revealed that the crystal structures of the powders synthesized by the two methods developed differently. After sintering, they showed different grain morphologies. Consequently, the electrolyte prepared from the two kinds of powders demonstrated different microstructures and different ionic conductivity. The electrolyte synthesized by sol gel methodology showed the highest ionic conductivity.
