“…The mixing can be accompanied by the reduction of particle size (comminution), or changes in their agglomeration state. Together, these phenomena of macroscopic motion of particles, comminution or agglomeration, and the potential for strain-induced dissolution of one phase into another (Vasil'ev et al, 2006;Vasil'ev et al, 2009;Vasil'ev and Lomaev, 2011;Vasil'ev, 2012;Butyagin, 1984;Butyagin, 2005) yields intimate mixing across lengths of scale. One must also keep in mind that many solid + solid reactions are exothermic, since no entropy is gained during the reaction.…”

Over the decades, the application of mechanical force to influence chemical reactions has been called by various names: mechanochemistry, tribochemistry, mechanical alloying, to name but a few. The evolution of these terms has largely mirrored the understanding of the field. But what is meant by these terms, why have they evolved, and does it really matter how a process is called? Which parameters should be defined to describe unambiguously the experimental conditions such that others can reproduce the results, or to allow a meaningful comparison between processes explored under different conditions? Can the information on the process be encoded in a clear, concise, and self-explanatory way? We address these questions in this Opinion contribution, which we hope will spark timely and constructive discussion across the international mechanochemical community.

“…38 The rate-limiting importance of each of these factors is system-dependent. [39][40][41][42] Moreover, in some cases the apparent rate may be instead limited by the chemical transformation itself. Understanding which factors limit the apparent rates in specific reaction types -for example BUMSis crucial to gain control over their transformations.…”

“…Al використовували елементарні порошки Al (чистота 99,5%, середній розмір частинок <150 мкм) та Cu (чистота 99,95%, середній розмір частинок <90 мкм). МЛ порошків здійснювали в атмосфері Арґону у планетарному млині Fritsch «Pulverisette-6» за режимів: 400 обертів/хв, 10 хв помел/ 5 хв пауза, співвідношенням маси розмелювальних тіл до порошкової суміші 8:1, тривалістю 2, 4 та 8 годин, яка відповідає введеній енергії в порошок 8, 16 і 32 кДж/г, оціненій за методикою Бутягіна і Стрелецького [24]. Після помелу впродовж 8 годин порошки спікались в графітових матрицях при температурі 900-950°C і тискові 30 МПа, причому швидкість нагріву/охолодження складала 40 К/хв, а витримка при максимальній температу-рі -5 хв.…”
