Model of structural transformations in a reactive dispersed medium under conditions of nongasifying combustion

Self-propagating high-temperature synthesis (SHS), a highly exothermic physical and chemical interaction of reagents in the condensed phase, is a method for producing a wide class of high-melting compounds. The methods of description of the processes in an SHS wave are initially based on the thermal theory. A model of nongasifying combustion is proposed in which the reactive diffusion processes are considered at the level of a mixture cell with allowance for the scale of heterogeneous and multistage transformations, which enabled to make the first quantitative estimates of SHS. However, the chemical composition and structure of the final product remain an open question.
