【Abstract】 In this work, nanometer zinc oxide powder was prepared with the method of homogeneous precipitation. The hearing treatment conditions of affecting the grain - size were studied. Research results of TG - DTA and XRD showed that the longer of the aging time, the higher of the calcinations temperature, the longer of the calcinations time and the slower of the temperature rising rate would lead to the increasing of the grain - size.更多还原
