Abstract

The paper deals with the influence of the phase composition and growth rate on the microstructure and electrical properties of alumina-zirconia eutectic composites. The presence of monoclinic zirconia can be detected by impedance analysis. Although the conduction activation energies of composites are similar to those reported for zirconia ceramics and single crystals, the conductivity of composites is lower..
