Abstract

Broadband dielectric spectra from 10 to 10 14Hz were acquired for 8 mol. % Y 2O 3/Yb 2O 3-stabilized zirconia (8YSZ and 8YbSZ) ceramics that related the dipole and ionic polarization losses to the absorption efficiency of electromagnetic irradiation. For 24 GHz irradiation, 8YSZ exhibited a higher absorption efficiency than 8YbSZ, resulting in a higher dielectric loss. The difference in the dielectric loss was interpreted as the difference in the loss of the dipoles originating from the fluctuations in the defect associations (Y′ ZrVö and Yb′ ZrVö).
