Abstract
Zirconia doped with ceramic oxides such as CaO, Y2O3 and Gd2O3 is a good structural material and a well-known ionic conductor. In the present study the electrical properties of gadolinium oxide doped zirconia at different temperatures were studied. The results show that the maximum conductivity of Gd2O3 stabilized zirconia can be obtained by adding 10 mol% of Gd2O3, which is necessary to form a fluorite type solid solution. Finally the electrical conductivity mechanism in zirconia which has been stabilized by adding different types of dopants is discussed.
