摘　　要：在水溶液中高能机械球磨金属粉末（水磨法）成功地制备了Mn3O4，Cu2O，Fe3O4等金属纳米氧化物以及Zn（OH）2和ZnO的混合粉末，在球磨过程中金属粉末表面反应层的不断剥落引发固液反应的发生。制得的粉末平均粒度在20-100nm之间。调整溶液的pH值可控制反应速率及产物的形成。Nano-partieles of metal oxides Mn3O4, Cu2O and Fe304 and powders of the mixture of Zn（ OH）2 and ZnO have been successfully prepared by high-power mechanical ball milling in water solution （wet milling process）. The solid-liquid reactions can be induced by the continuous peeling-off of the reacted layer on the surface of the powder during milling. The mean size of the as-prepared particles is about 20 - 100 nm. The reaction rate and the product formation can be controlled by adjusting the pH value of the solution.
