| 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20～100 nm之间。调整溶液的pH值可控制反应速率及产物的形成。

| Abstract: | Nano-particles of metal oxides Mn3O4, Cu2O and Fe3O4 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. |
