ball milling generated

Ball milling(solid-state synthesis) is one of the most important processes used in industry to synthesize nanomaterials, and is also called mechanical alloying or attrition. This method is based on a top-down approach, like self-assembly of molecules and reducing the size of the larger particles.

    Apr 22, 2016· Duringball milling, up to 80 % of the energy that isgeneratedin the mill is dissipated as heat. This is why measurement and control of the temperature in theball millsis important, for example, if heat-sensitive products are formed that would be degraded, or side reactions that would be favored at high temperatures [6, 7].
