Generation and Superposition of Concentration and Heat Waves Under Exothermic Reactions in Powder Systems

  • V. P. Solntsev
  • T. A. Solntseva

The superposition of reaction waves, leading to energy concentration in local regions, is revealed in studying the thermal kinetics of interaction in mixtures with exothermic reactions during contact melting. The local energy relaxes through spontaneous emission of charged particles. This influences the thermal electromotive force and allows the dynamics of reaction wave interaction to be followed in the process. In these cases, synthesis and reaction sintering are uncontrolled.
