Abstract

This paper presents an experimental study of the shock compression of an emulsion matrix based on an aqueous solution of ammonium and sodium nitrates at pressures up to 37 GPa, which is significantly higher than the calculated detonation pressure. The data obtained were used to determine the parameters of the Hayes equation of state and calculate the shock heating temperature of the matrix. At a pressure of more than 17 GPa, the input pressure profiles shows a rise associated with the chemical transformation of the emulsion.
