Abstract
The addition of 30 mol % of different zirconia containing powders: cubic stabilized zirconia (8YSZ), te-tragonal zirconia (TZ3Y), and TZ3Y+20 wt. % Al2O3 (3Y-20A) to barium titanate (BaTiO3) was studied. X-ray diffraction analysis of the sintered compact made of these powder mixtures confirmed the presence of single phase peroviskate-like structure. The microstructure of the sintered samples showed different grain sizes, for different kinds of zirconia additives. The relative permittivity and the dielectric loss of the sintered pellets were measured at zero and room temperatures. The highest relative permittivity was ob-tained for samples having 30 mol % TZ3Y. It was 5300 at zero temperature and 2250 at room tempera-ture at 1kHz. The samples sintered at 1350oC showed lower values of the dielectric losses than those sin-tered at 1400oC.
