Ball Milling - an overview ScienceDirect Topics

A study proposed the importance of ball milling in synthetic organic chemistry, which has been widely documented [110]. Many reports in the literature have shown that high-speed ball milling (HSBM) is appropriate for a variety of organic transformations and for the expansion of environmentally benevolent chemical reactions [111, 112]. HSBM in solvent-free circumstances is considered as a ...

Ball milling is one of central techniques of mechanochemical synthesis, that is, chemical synthesis by the action of mechanical force, such as by grinding, stretching, or shearing. Mechanisms underlying chemical reactions in ball milling involve abrasion, shearing, and friction, making ball-milling chemistry one of central areas in tribochemistry.

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 is, furthermore, a way ...
