中文摘要：

用干法室温振动研磨方法制备纳米Zn粉,化学沉淀法制备纳米Fe3O4,纳米Zn和Fe3O4水解制备纳米ZnFe2O4。TEM和XRD检测显示经11h研磨的Zn粉粒度分布在10～20nm之间,纳米Fe3O4的粒度分布在20nm左右,水解产物纳米ZnFe2O4,形貌为方形片状,粒子尺度约为20nm。研究结果表明纳米Zn/Fe3O4摩尔比为1.5∶1,反应温度为300℃是最佳反应条件,可见用振动研磨方法制备的纳米Zn颗粒具有优良的性能,能使化学反应在较低温度下快速完成,且制备方法简单易行,便于批量化生产。

英文摘要：

Zn nano-particles were prepared by a dry roller vibration milling at room temperature,Fe3O4 nanoparticles were prepared by chemical precipitation method,and then ZnFe2O4 nano-particles were manufactured by hydrolyzing Zn/Fe3O4 nano-particles.TEM and XRD tests showed that Zn particles size milled 11h was the range between 10 and 20nm,Fe3O4 particles size was about 20nm and the solid product of the hydrolysis was also about 20nm with quadrate nano-flake morphology.The research indicated that it was optimal reaction condition for making ZnFe2O4 when reaction temperature was 300℃ and mol ratio（Zn：Fe3O4）equal to 1.5：1.It is obvious that Zn nano-particles milled 11h provided with excellent performances,which could make the chemical reaction complete rapidly in a lower temperature.The preparation method was comparative simpleness and prone to a batch production.
