On the development mechanism and kinetics of the explosive mechanochemical synthesis

Mechanochemical Synthesis of Fe–S Materials

“…Although the principles governing these reactions in many cases are incompletely understood and are also undoubtedly system specific, the formation of many compounds prepared by mechanochemical reactions, for example, borides (7), carbides (8,9), and silicides (10,11), has been reported in the literature. However, relatively few studies of synthesis of metal sulfides have been published (12)(13)(14)(15)(16)(17)(18)(19)(20)(21). On the other…”

Properties and Reactivity of Mechanochemically Synthesized Tin Sulfides*1

“…The application of mechanosynthesis using for high-energy grinding enables the mixing of components on the atomic level, a shift of the reaction regime from diffusion to kinetic or close to kinetic and a preparation of products with maximum interfacial area/total volume ratio (1)(2)(3). Since it is possible to study the progress of mechanosynthesis using various identification and/or analytical methods, it is also possible to prepare partially or totally synthesized tin sulfides with controlled structures (4)(5)(6)(7)(8)(9)(10)(11).…”

Milling Dynamics and Propagation of Mechanically Activated Self‐Sustaining Reactions

“…Ignition represents a crucial aspect of MSRs and, thus, significant attention has been paid to its study [20,[26][27][28][29][30][31][32][33][34][35]. In particular, systematic experimental investigation aimed at measuring the activation time preceding the ignition of the MSR, commonly referred to as the ignition time, which has been shown to depend on several factors including chemical composition, impact energy, amount of reactants, and temperature [20,[26][27][28][29][30][31][32][33][34][35].…”

“…Nevertheless, the direct experimental investigation of the propagation process raises considerable difficulties due to the rapid motion of the reactor, the violent stirring of the powder charge, the scarcely predictable ignition time, and the high rate of chemical conversion. Overall, such factors translate into fragmentary and contradictory empirical evidence simply suggesting that MRSs do not result necessarily in the complete conversion of reactants to products and that the variation of BM conditions can even determine the suppression of MRSs [20,[26][27][28][29][30][31][32][33][34][35]. Nevertheless, detailed information on the way milling dynamics can affect MSRs is highly desirable in view of a reliable exploitation of MRSs in materials manufacturing contexts.…”
