Equations of state of silver azide and calculation of its Hugoniots

The thermal and caloric equation of state of the orthorhombic phase of silver azide are presented. For this material, pressure–temperature relations along the Hugoniots of the material with different porosity and shock velocity–particle velocity relations are calculated. The calculations are performed for pressures up to 3 GPa and temperatures of 300–500 K, particle velocities of up to 0.4 km/s, and initial porosity of 1–1.5. The relative positions of the Hugoniots and equilibrium lines of polymorphic transformations of silver azide in the indicated region of thermodynamic variables is discussed.
