Zusammenfassung:Theoretical analysis of nonequilibrium decomposition of transition metal compounds with elements forming diatomic phases is performed. Solution of the mathematical model for an open nonequilibrium system makes it possible to establish the nonmonotonous nature of the changes in component concentration. It is concluded that there are thermokinetic oscillations leading to the occurrence of dissipative structures.
