| Ceria based ceramic materials are the possible constituents as electrolytes in electrochemical devices. Doping of trivalent ion having lower melting point with ionic radius close to host ion radius, decreases sintering temperature and enhances ionic conductivity of ceria based electrolytes. This paper attempts to unveil the complicate interconnection between gadolinium doped ceria co-doped with bismuth (3+) ion. It is successfully made into a unified entity by solid state reaction synthesis. The synthesised sample is characterised using XRD, EDAX, FTIR, SEM, and electrochemical impedance spectroscopy. Nanocrystalline particles are obtained with cubic fluorite structure at a relatively low processing temperature. Rod shaped grains are formed for the sintered sample. The ionic conductivity of the samples is comparable to that of gadolinium doped ceria electrolyte. |
