Combustion of thermite systems in thin layers with an open surface

SHS combustion of thermite compositions in the form of thin layers without formation of a continuous layer of cast products is studied. It is shown that combustion of thin layers of high-temperature compositions can be accompanied by almost complete dispersion of liquid-phase combustion products. The height of filling material and the caloric content of the mixture are effective parameters to control the size of the dispersed particles of cast synthesis products. It is established that the macrostructure of synthesis products is formed in the vicinity of the combustion wave through coalescence and capillary drift of metal droplets.
