Mechanical Properties of Scandia Stabilised Zirconia with Alumina Addition
Zirconium oxide doped with scandium oxide is one of the most promising materials for electrolytes of solid oxide fuel cells because of its high ionic conductivity. In this study, temperature dependence of mechanical property, especially strength, of 9 mol% scandia doped zirconia polycrystalline samples with 0 to 30 wt% of alumina additions was examined at temperatures from 293 to 1273 K. Ionic conductivity was also measured by AC impedance analysis. From both mechanical and electrical standpoints, the experimental results were discussed in terms of alumina addition.
