Abstract: Nanometer ZnO particles were synthesized by the homogeneous precipitation method from urea and zinc nitrate. TEM analysis shows that nanometer ZnO particles obtained are in the
nanosize range of 50nm; BET analysis shows that the specific surface area of the ZnO particles is 25.6m2/g; XRD analysis shows the crystalline
of the nanometer ZnO particles is in the hexagonal structure; the formation mechanism of nanometer ZnO particles was concluded by the analysis of XRD,
IR and TG-DSC.

Key words: nano-zinc oxide, homogeneous precipitation, mechanism
