%X ZnO nanoparticles were synthesized by the mechanochemical processing. XRD patterns indicate all products are single ZnO phase while ZnS04/NaOH(mol ratio)is in the range from 1/2.1 to 1/3.0, and ZnO yield will obtain the maximum when ZnSO4/NaOH(mol ratio) is 1/2.5. TEM micrographs show the particle size of ZnO is about 40~80nm. The heat released by the solid-solid reaction of ZnSO4 and NaOH makes the product of Zn(OH)2 tramsform directly to ZnO particles. The optical absorptivity of ultraviolet (200-400nm) for nanometer ZnO is much better than that of normal ZnO powders.
