Abstract

The electrical conductivity of hot-pressed magnesia (HPM) was investigated as a function of porosity in the temperature range 500-900 degree C. The conductivity decreases with increasing porosity. The activation energy of the conductivity varies between 1. 2 and 2. 0 eV in the temperature range 650-900 degree C. It is suggested that the electrical conductivity in HPM is controlled by enhanced oxygen diffusion along the grain boundaries.
