文摘

Gd3+ doped ceria at different pH were synthesized by EDTA-citrate complexation. Crystallite sizes of calcined GDC powder decreases with increase of pH. Raman spectrum of sintered GDC powder confirms the formation of solid solution. FE-SEM images of GDC shows well defined grains separated from grain boundaries. GDC at pH = 10 exhibits the highest oxygen ionic conductivity of 1.6 × 10−2 S cm−1.
