Study on the Frequency and Temperature Dependent Electrical Properties of MnO and PbO Doped ZnO Nanoceramics

Abstract

This work reports the temperature and frequency dependence microstructure, electrical of MnO and PbO doped ZnO nanoceramic synthesized by solid state reaction method. The as-sintered ceramic varistors with different compositions have been characterized via laboratory X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and electrical measurements. It has been observed that MnO and PbO doping on ZnO plays a remarkable role in improving its structural, electrical and dielectric properties (XRD) pattern confirmed the single-phase hexagonal wurtzite structure of the samples without having any other intermediate phases. AC resistivity has been found to be decreased while the conductivity increased with the increase in doping.

Solubility of Mn in ZnO Crystallites Synthesized Using Solid State Techniques

“…These suggest the incorporation of Mn ions into the lattice of the hexagonal wurtzite structure of the ZnO. In the work of Mobarak et al [17], MnO and PbO doped ZnO nanoceramic was synthesized by solid state reaction method using 1%, 1.5%, 2.0% and 2.5% of the various dopants. In synthesizing the samples, powders of MnO, PbO and ZnO were ground in the appropriate ratio and ball milled.…”
