Thermodynamic parameters of mixtures with silicon nitride under shock-wave impact in terms of equilibrium model

The results of numerical experiments on the modeling of the thermodynamic parameters of the shock-wave loading of silicon nitride $\rm Si_3\rm N_4$ and mixtures based on it are presented. A thermodynamically equilibrium model is used to account for the phase transition of $\rm Si_3\rm N_4$ during the shock-wave impact. The thermodynamic parameters of shock-wave loading are described for pure silicon nitride, as well as for mixtures of $\rm Si_3\rm N_4$ with potassium bromide $\rm KBr$, periclase $\rm MgO$, and aluminum nitride $\rm AlN$. The computation results are compared with experimental data obtained by different authors.
