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. The principal advantages of ball milling over conventional methods of chemical synthesis are (1) enabling chemical reactions in the absence of solvents, therefore resulting in a cleaner synthetic procedure, (2) obtaining products that are difficult or impossible to obtain in the presence of bulk solvents, and (3) expanding the scope of chemical reactions to slightly soluble or inert starting materials.
