Abstract: Nanometer ZnO particles were synthesized by evaporating of zinc powders of averageparticle size of 370μm studied by XRD, TEM and electron diffraction. The particleswere formed by the oxidation of evaporated zinc vapor in the air. It was found that theparticles range from 70 to 100nm in average particle size. The effect of experimentalparameters was investigated, the increase of the air flow-rates reduced the averageparticle size, while increasing the evaporation temperature and the amount of metalcharged increased the average particle size. TEM of the particles collected showedthat the crystal habits of particles have a tetrapod-like of wurtzite structure consists offour needle crystals. It was found by electron diffraction that all particles were singlecrystal.
