Abstract

The paper presents the results of theoretical and experimental studies of establishing the patterns of phase formation under vacuum heating conditions. The mathematical model includes the heat balance equation and kinetical equation system for eleven chemical reactions. The law of acting masses and Arrhenius law are used to write the kinetical equations. Semi–empirical methods are employed to calculate formal-kinetical parameters. The multiphase product forms in experiment and in numerical model. The numerical calculations obtained qualitatively agree with the experimental results.
