Factors controlling thermoluminescence from self-propagating high-temperature synthesis in powder bodies

Computer simulations are used to study the physicochemical processes that determine the light emission from the lateral surface of the sample during self-propagating high-temperature synthesis (SHS) in the Ni-Al powder system. It is shown that endothermic phase transitions in the components of the powder mixture control the character of change of the chemiluminescence intensity. The behavior of the emission from of the subareas of the lateral surface carries information about the parameters of state of the medium and physical mechanisms underlying SHS.
