The application of nanoparticles in the processes of making commercial products has increased in recent years due to their unique physical and chemical properties. Materials whose crystallites, particle sizes are smaller than 100 nm are commonly named nanocrystalline, nanostructured, nanosized materials. There are many methods used for the preparation of nanomaterials. We use is a method which is easy if compared to other methods with the chemicals required for these methods are available and cheap. Nano zinc oxide has been prepared by wet chemical method from zinc nitrate and using sodium bicarbonate as precipitation agent. The resulting nanopowders were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM).The particle size measurement using XRD Scherer’s formula calculations confirms that the crystallite size of the ZnO nanoparticles range from 41 to 67 nm and depending on calcinations temperature. SEM micrographs reveals less number of pores with smaller lump size in addition to clearly showing the micro structural homogeneity and remarkably dense mode of packing of grains of ZnO nanoparticles with minimum porosity.
