Abstract

Twenty cation per cent yttria doped ceria Ce0.8Y0.2O1.9 was prepared by an optimised oxalate coprecipitation route to give fine sinterable powder. This was formulated into slurries for tape casting of the doped ceria solid electrolyte used in solid oxide fuel cells. Prior dry milling of the powder was found to be most effective to further reduce the average agglomerate size, which allowed to sinter dense membranes at 1400°C for 2h, among the best results obtained so far for tape cast doped ceria. Ball milling of the powder, composition and viscosity of the slurry as well as sintering conditions of different tapes are discussed.
