AB - In order to improve electrical conductivity and mechanical properties of 8YSZ SOFC electrolyte material, we
used Al2O3 as an additive and applied the spark plasma sintering (SPS) method. The sintered bodies were densified above
96 % of theoretical density at 1200oC and possessed microstructures composed of homogeneous grains less than 1 μm in
size. The addition of Al2O3 improved fracture toughness and bending strength by inhibiting grain growth of 8YSZ and increased
total ionic conductivity because grain interior conductivity appeared to remain constant and grain boundary conductivity
increased. It was assumed that the dissolution of Al2O3 into 8YSZ which was inevitable problem at commercial sintering
method was effectively prohibited by the SPS technique with a relatively low sintering temperature and the reaction
between Al2O3 and SiO2 present at grain boundary to produce the crystalline Al2 − xSi1 − yO5 phase, resulting in the increase
of grain boundary conductivity.
