Energetic materials generate high energy under rapid combustion or explosion in a chemical reaction. They include nitro, nitramin, nitrate and azide compounds, and oxidizer and fuel mixtures, all of which are used in a variety of fields. The maximum detonation propagation velocity of such materials is about 10km/s, sometimes accompanied by shock waves. During the reaction process, pressure may reach hundreds of thousands of atms and temperatures may reach thousands of degrees C. To use such materials safely, their explosive reaction mechanisms and accompanying air blast must be studied. The Institute studies the thermo-dynamics and hydrodynamics of such materials at ultra-high pressures and temperatures, clarifies the decomposition reaction mechanism by shock and heat, and conducts quantum chemical research into molecular design and stability.
