Abstract

Air- and vacuum-fractured samples of calcium-doped beta-alumina have been examined using Auger electron spectroscopy. The calcium concentrations at grain boundaries were found to be enhanced over the bulk value by about a factor of 10. Excess sodium was observed on the fracture surface of air fractured electrolytes, and was absent for samples fractured in ultra-high vacuum. Temperature-dependent features in the secondary electron spectrum and the effects of surface charging and radiation damage by the incident electron beam were also observed.
