Abstract
A mathematical model of synthesis in a mechanically activated SiO2 + Al mixture is constructed in the macroscopic approximation. It is demonstrated that preliminary mechanical activation makes it possible to obtain solid-phase ignition and to ensure synthesis of Al2O3 and Si products in the thermal explosion regime. Based on experimental data, thermophysical and thermokinetic constants of the process are determined.
