Abstract
The specific features of dynamics of the thermal explosion in systems porous reagent–active gas–solid product under conditions where the heat‐transfer and mass‐transfer regions are separated from the ambient medium are considered. In addition to the competition of heat release and heat removal, the process of initiation of exothermal chemical interaction in these systems under normal pressures depends significantly on conditions of filtration transport of the gaseous reagent. The induction and post‐induction periods of the thermal explosion are studied. The theoretical analysis of thermal‐explosion issues is supplemented by an experimental study of the process for the porous titanium–nitrogen–titanium nitride system.
