摘要
Hard zinc from thermo plating zinc factory had been treated for preparation of ZnO nano powder by chemical precipitation. The ion type and non ion type surface active reagents were added in different steps and ultrasonic agitation was used in preparing process. TG/DTG was applied to determine thermo decomposition temperature of the precursor as about 450 ℃. The product is light yellow, and had been characterized by XRD, S BET and TEM, through which the good dispersing sphere particles with the average diameter of approximately 5060 nm are observed, and the crystal is pure ZnO with hexahedral structure. The cost of preparing nanometer zinc oxide is low.
