【Abstract】 Nanometer zinc oxide powder is prepared by using precipitation thermolysis process from zinc chloride and sodium carbonate The structure and morphology of nanometer particles are investigated by means of TG DTA,XRD and TEM The results show that the effect of thermolysis reaction on the structure and morphology of the powder is stronger than the precipitation reaction The well crystallized and dispersed,homogeneous,nanometer zinc oxide with 10nm in diameter is available under the experiment condition The process is easy operation and convenient to commercial scale更多还原
