Polycrystalline samples of PZTN with the compositions Pb1.1-x/2 (Zr0.53 Ti0.47)1-x NbxO3 (where x=0.00, 0.01, 0.02, 0.03, 0.04, and 0.05) has been prepared by solid state reaction method. X-ray diffraction studies suggest that the compounds are in rhombohedral phase. Pyrochlore value and surface morphology was studied by scanning electron microscope (SEM). Detailed studies of dielectric constants as a function of temperature (40oC-500°C) and frequency (100Hz-1MHz) suggest that the compound do not have relaxor behavior and undergoes diffuse type of phase transition.

Keywords:   Dielectric, ceramics, XRD, SEM.
