Macrokinetics of Mechanosynthesis in Solid-Gas Systems.I.Mathematical Simulation

摘要

A mathematical model for mechanosynthesis in solid-gas systems is constructed which includes the equations of mechanical-reactor heat balance,grinding,the excess-energy dynamics in the condensed substances,which determines the effect of mechanical activation on the chemical-reaction rate,and the reaction kinetics.A brief analysis of the model is presented.A description is given of two simplified models of independent significance derived from the general model,which can be studied by analytical methods.Synthesis in a preactivated system is studied in detail.Relations determining the characteristics of the synthesis are obtained.The accuracy of the analytical estimates is verified by numerical simulation.
