High energy ball milling process for nanomaterial .Traduire cette page

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).

Temperature progression in a mixer ball mill | .Traduire cette page

During ball milling, up to 80 % of the energy that is generated in the mill is dissipated as heat [ 5 ]. This is why measurement and control of the temperature in the ball mills is 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 ].

High-energy ball-milling was used in several works to produce nano-LN. Spex Mixer Mill 8000 is one of the most commonly used ball mills for this purpose. In general, dry grinding with one ball with a diameter of around 1 cm was used in these processes with grinding times as long as 5–20 h [13,15,20–22] and even longer than 100 h [23]. At the beginning, the grain size rapidly decreased with ...
