Abstract

Structural properties of the compounds were examined using an X-ray diffraction (XRD) technique to confirm the formation of phase at different temperature. The electrical current response for equivalent circuit of PZT-5A, resonant frequencies, antiresonant frequencies and mechanical quality factor were studied by numerical simulation and compared with experimental results. The dielectric properties of PZT-5A ceramics in the temperature range 50 -200ºC were measured. The effect of grain size of the PZT-5A on the dielectric constant and dielectric loss were investigated. As the grain size increased, the maximum dielectric constant increased. The dielectric study with frequency at different temperature in the frequency range 1 to 5 MHz shows that dielectric constant decreases with increasing frequency. Loss factor does not vary with frequency but it becomes independent of higher frequency range.
