Characterization of Energetic Materials at Extreme Conditions

Download Project Report (Phase 2, Year 4)

Project Description

This project investigates phase and chemical stabilities of selected energetic materials at the blast-relevant pressure, temperature, and different chemical environments using diamond anvil cells (DAC) and dynamic-DAC coupled with confocal micro-Raman spectroscopy and third-generation synchrotron X-ray diffraction.

The research objectives are to:

  • Measure fundamental thermoelastic properties in both static and dynamic conditions
  • Determine the crystal structure, phase transition, and chemical reaction
  • Evaluate the detonability of energetic materials.

The project is significantly relevant to the Homeland Security Enterprise by:

  • Providing fundamental data for energetic materials libraries and thermochemical models, which is critical to developing a predictive capability
  • Developing new chemical and spectroscopic methodologies to detect explosives
  • Enabling the timely and “small-scale (<1 mg)” evaluation of the detonability and sensitivity of newly developed and/or emerging energetic materials.
We will continue to determine static properties of other energetic materials of high value to DHS – including reactive metals, composites and thermite mixtures. As well as to investigate dynamic properties of reactive and energetic materials that are emerging threats to homeland security.
