Abstract
Electrical conductivities of Al2O3/A1 composite synthesized by directed oxidation of an aluminum alloy, and sintered Al2O3–4% MgO are measured. The high conductivity of the Al2O3/A1 composite compared to sintered Al2O3–4% MgO is shown as proof of the presence of continuous metal channels in the composite. Furthermore, the conductivity data are used to determine the activation energy for the diffusion of the dominant charge carrier in the oxide matrix.
