    Abstract

    The ferroelectric, dielectric and piezoelectric13; properties of compositions Pb1x2013;xCex (Zr0.60Ti0.40)O3,13; (x = 0.0, 0.01, 0.02, 0.04, 0.06 and 0.08) are studied. The13; above compositions are prepared from their constituent13; oxides, calcined at 900 C for 4 h and various phases13; present are characterized by X-ray diffraction (XRD)13; technique. The above powders are uniaxially pressed into13; circular compacts, sintered at 1,250 C for 2 h, electroded,13; poled at 2 kV/mm D.C. voltage and their electrical properties13; are measured. The XRD analysis shows the presence13; of rhombohedral phase up to 2 mol% ceria while tetragonal13; phase found at higher concentrations. It is observed that13; the ferroelectric, dielectric and piezoelectric properties13; increase with the addition of ceria with a maximum at13; 2 mol% and then decreases. The higher piezo properties13; associated with low ceria concentration are attributed to13; rhombohedral phase.
