Abstract

Within the scope of the previously developed by the authors thermokinetic model of reacting in a peritectic system based on the synergetic approach taking into account the temperature dependence of the equilibrium concentration of the refractory component in the liquid phase by computer experiments it was established the existence of different kinds of kinetic trajectories of the reaction process, which is due to the nonlinear dependence of the concentration function of refractory component in the melt from temperature. As a consequence the initial thermal process conditions so as the rate constants of the elementary processes determine the nature of the trajectories of the process.
