• Reactive ball milling to produce nanocrystalline ZnO

    2008-09-15· Ball milling can also induce chemical reactions that do not normally happen at room temperature. Particularly, milling can induce combustion reactions for some metals (Zr, Ti, Fe and Sn) in oxygen,leading to their transformation to oxides. Therefore, reactive milling can be an alternative technique to produce oxides from metals. Since ball
