Abstract

Impedance spectroscopy with millimeter-scale electrodes was used to determine the local grain-boundary resistivity (ρ gb) of a 1-mol%-Al 2O 3-doped CaO-stabilized ZrO 2 (CSZ) specimen. A much higher ρ gb at the specimen surface was observed compared with that of the specimen interior. The result was mainly due to the difference in the dihedral angle of the intergranular phase, which was ∼20° at the surface and ∼100° at the interior.
