  • High energy ball milling process for nanomaterial synthesis

    Besides materials synthesis high-energy ball milling is a way of modifying the conditions in which chemical reactions usually take place either by changing the reactivity of as-milled solids (mechanical activation — increasing reaction rates lowering reaction temperature of the ground powders)—or by inducing chemical reactions during milling (mechanochemistry). It involves the use of a high energy ball mill to initiate chemical reactions and structural changes.
