“…Finally Zn and CO/CO 2 vapors reacted with together that its resultant appearance the ZnO nanocrystals. The advantage of this method is considerable reducing of the decomposition temperature of ZnO in presence of the graphite [6]. Another synthesis method for ZnO nanoparticles without using of catalyst in large scale is heat the Zn foil in the air furnace without using of additional gas by 700 0 C. With controlling the heat rate, much morphology like nanowires, nanotubes, nanoneedles, nanotetrapads have achieved [7].…”

ZnO is a semiconductor with direct band gap that because of its optical and electronically properties has very interesting for researchers. Wide application of this compound in electronic and optic like piezoelectric transducer, gas sensor, optical waveguide, thin conductor layer and transparent, varistors, photocells, optical U.V. equipments and also variety medical applications with concerning its nature friendly cause that to find the economical method for mass production be concerned. During recent decay, many methods such as sol-gel, wet chemistry, CVD & MOCVD, hydrothermal methods and development process have been invented for ZnO production. The most common problems of these methods are complexity of production process, need to expensive equipments, need to expensive raw materials, need to exceedingly pressure and temperature etc. In this research with activation of Zn as the raw material, nanoparticles of ZnO has been product by a planetary mill and hydride action that this method has ability to extensile in industrial range.SEM investigations approve the nanosize of produced particles. Morphology of particles is more similar to hexagonal crystal structure. Process efficiency is 100 percent and x-ray diffraction (XRD) of resultant powder verifies this. After synthesis and characterization of ZnO nanopowder as one of its application, varistor was made and then electrical property of this part was evaluated.
