Using XRF, a qualitative analysis had carried out to investigate that the samples contain lead, titanium and zirconium. The samples were pressed as pellets 10mm diameter and 1mm thickness. Then sintered at 1100°C. Using high voltage generator a poling process were achieved at (0.5-1.5)KV/mm at room temperature. Using AC measurements, dielectric constant including real and imaginary parts where studied in a function of frequency in the range (20Hz-3kHz) for poled and unpoled samples at room temperature. The dielectric constant including real and imaginary parts were studied too in a function of temperature at constant frequency. Pyroelectric current was measured in order to calculate the pyroelectric coefficient of the material.

Using XRF, a qualitative analysis had carried out to investigate that the samples contain Lead, Titanium and Zirconium. The samples were pressed as pellets then sintered at 1100C. Using high voltage generator a poling process were achieved at (0.5 1.5) KV/mm at room temperature. Using AC measurements, a relative permittivity including real and imaginary parts in a function of frequency in the range (20 Hz-3 kHz) for unpoled samples at room temperature were measured in order to investigate the polarization processes. The relative permittivity and loss factor for poled samples were studied in a function of frequency where the poling process results in increasing the relative permittivity and decreasing the loss factor. The relative ...
