Abstract

Nano-sized Ce1-xGdxO2-0 5x (O < x < 0.3) powders, with a narrow particle size distribution in the 5-10 nm range, were synthesized via a soft chemical route. The obtained materials were highly sinteractive and their grain growth was strongly controlled by gadolinium dopant content. Selected fast firing and conventional sintering processes were used to tailor the dense microstructures of the electrolytes. The combined effects of grain size and dopant content on the electrical properties was evaluated taking into consideration the bulk and the grain boundary of the final microstructures. A careful control of the sintering parameters is crucial for the fabrication of tunable microstructures of nanoelectroceramics for IT-SOFC components.
