Mobarak H, Paul SC, Islam MS, Akter S and Sohag K

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.
