In a 15-mol%-CaO-stabilized zirconia (CSZ) specimen, the grain boundaries at the surface region exhibited a lower electrical resistance than those at the inner region. However, when up to 1.5 mol% Al2O3 was added, the grain boundaries at the surface showed a higher resistance. These results were explained in terms of redistribution of the intergranular-liquid phase during CSZ sintering.
