Abstract

A binary solid solution of 0.5BaZr0.2Ti0.8O3-0.5BaCe0.02Ti0.98O3 ceramics was synthesized by solid state reaction technique. The phase formation was determined via X-ray diffraction technique. The bulk density was measured using Archimedes’ method. The result showed that the sample was a single phase perovskite and 5.85 g/cm3 for a bulk density. The relative permittivity of ceramic with Ag electrodes showed a frequency and temperature dependence. The relative permittivity decreased from 3,164 to 2,354 for measured in the range of 500Hz-2MHz at room temperature which the loss tangent had lower than 0.07 in this frequency range. The broad relative permittivity peak was found which a maximum was ∼7,139 at Tm= 95 °C and 1 kHz. Moreover, the ferroelectric properties were characterized and discussed with previous related works.
