Evidence of induced structural and conduction anisotropy in scandia-stabilized zirconia ceramics



Evidence of current induced structural and conduction anisotropy was experimentally established in scandia-stabilized zirconia ceramics. It was found that these effects are observed only when the material is in the rhombohedral phase. It was shown using conductivity measurements and X-ray phase analysis that anisotropic behavior of polycrystalline ZrO2-Sc2O3 ceramics is induced by a low-amplitude alternating current in the temperature range corresponding to a rhombohedral-to-cubic phase transition.
