The effect of the glycine content on the particle size, morphology, and sintering behavior has been studied by changing the glycine-to-nitrate (G/N) ratio during the combustion synthesis. A range of techniques including thermal gravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), specific surface area determination (BET), particle size analysis (PSA) and scanning electron microscopy (SEM) were employed to characterize the GDC powders prepared. From the dilatometric studies, it is observed that the GDC powders prepared with a G/N ratio 0.55 show superior sintering activity compared to GDC powders prepared with a lower GIN ratio. A sintered GDC sample showed an ionic conductivity of 2.01 X 10(-2) S/cm at 600 degrees C in air.
