Abstract:

This report detailed the preparation of pure and doped ionic solids, characterization of the defect structure, and the correlation of electrical transport properties with the defect structure. The three materials systems investigated were zirconia-base, thoria-base, and beta alumina. The zirconia monoclinic-tetragonal transformation was characterized as martensitic and a revised phase diagram for the system ZrO2 - YO1.5 system was proposed. In the thoria-base system, electrical conductivity measurements in air indicated that isothermal conductivity increased with CaO content and reached a broad maximum. The electrical conductivity of sodium doped beta and beta double prime Al2O3 was found to be a function of sodium content, frequency, temperature and type of electrode employed.
