✦ Synopsis

The ionic and electronic conductivities of polycrystalline indium and gallium p-alurninas were measured. The conductivities were measured using @arising electrodes with nc frequency analysis which was also used to determine the relative contributions of bulk and grain boundary conductivity to the conduction process. A higher value of the conductivity was obtained using molten salt electrodes and this effect was thought to be due to the Penetration of the salt into cracks in the Pellets. The electronic conductivities were measured using the Wagner asymmetric polarisation technique and were found to play a negligible part in the conduction process.
