Abstract
Pure ceria and ceria-yttria solid solution powders with formula Ce1-xYxO2. where 0 < x < 0.30 were prepared by the coprecipitation-calcination method. The samples were sintered at 1250-1600°C for 2 hours. The XRD method was used to determine cell parameters of the samples. Their electrical properties were investigated by ac impedance spectroscopy in the temperature range of 100-700°C in air. It was found that the electrical conductivity, fracture toughness, and flexural strength of the samples increase with yttria concentration and reach a maximum for Ce0.85Y0.15O2. The obtained material seems to be a promising solid electrolyte for IT-SOFC.
