Solid oxide components such as electrolyte for solid oxide fuel cell require chemical stability and high conductivity. Substituting Zr for Ce in BaCe0.8Nd0.2O3-δ improves the chemical stability but reduces conductivity. The objective of this work was to study the optimization of conductivity and chemical stability by changing the ratio of Ce to Zr in BZCN. Perovskite type BaZrxCe0.8-xNd0.2O3-δ (BZCN) powders were prepared by an EDTA–citric acid (EC) process. BaZrxCe0.8-xNd0.2O3-δ (x≥0.4) oxides show good chemical stability against carbon dioxide. The conductivities of sintered samples increased with the temperature and decrease with their Zr content. The good chemical stability and conductivity of BaZr0.4Ce0.4Nd0.2O3-δ is potential to be practically used with both high conductivity and good stability
