Features of controlled volume synthesis of composiyes
In this work, the regularities of volume synthesis of composite in cylindrical reactor was analyzed taking into account the main controlling parameters. The model infers the study of temperature distribution in the reactor volume depending on the properties difference between reagent and reactor walls and on parameters of two summary chemical stages. First of reactions correspond to the synthesis of oxide inclusions; second one corresponds to the matrix formation. It was shown that, for different particular cases of the heating process controlling, the practical adiabatic conditions for reactions, the classical thermal explosion at the conditions of the heat exchange with environment, the dynamical initiation of reactions at different heating rates and the synthesis mode during temperature decrease with the formation of irreversible composition could be realized. All called modes of the synthesis are realized experimentally.
