    In the ball milling process, the force of grinding and impacting between balls and powders resulted in the defects in powder particles, e.g. dislocations and compound twins. Such defects existing in the powders lead to the lattice distortion and increase the system energy of the powder composites.

  • 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).
