Hugoniot adiabat of a quartz-aluminum mixture

The Hugoniot adiabats of mixtures of quartz with aluminum are calculated with and without allowance for the chemical interaction of the components behind the shock front. It is shown that the results of experiments at pressures above 25 GPa can be explained not only by the faster phase transition of quartz to stishovite in the mixture but also by the formation of aluminum and silicon oxides behind the shock front.
