Developing and testing novel energetic materials is an expanding branch of the materials sciences. Reaction, detonation or explosion of such materials invariably produce extremely high pressures and temperatures. To study the equations-of-state (EOS) of energetic materials in extreme regimes both shock and static high pressure studies are required. The present volume is an introduction and review of theoretical, experimental and numerical aspects of static compression of such materials. Chapter 1 introduces the basic experimental tool, the diamond anvil pressure cell and the observational techniques used with it such as optical microscopy, infrared spectrometry and x-ray diffraction. Chapter 2 outlines the principles of high-nitrogen energetic materials synthesis. Chapters 3 and 4, examine and compare various EOS formalisms and data fitting for crystalline and non-crystalline materials, respectively. Chapter 5 details the reaction kinetics of detonating energetic materials. Chapter 6 investigates the interplay between static and dynamic (shock) studies. Finally, Chapters 7 and 8 introduce numerical simulations: molecular dynamics of energetic materials under either hydrostatic or uni-axial stress and ab-inito treatments of defects in crystalline materials. This timely volume meets the growing demand for a state-of-the art introduction and review of the most relevant aspects of static compression of energetic materials and will be a valuable reference to researchers and scientists working in academic, industrial and governmental research laboratories.

David I.A. Millar's thesis explores the effects of extreme conditions on energetic materials. His study identifies and structurally characterises new polymorphs obtained at high pressures and/or temperatures. The performance of energetic materials (pyrotechnics, propellants and explosives) can depend on a number of factors including sensitivity to detonation, detonation velocity, and chemical and thermal stability. Polymorphism and solid-state phase transitions may therefore have significant consequences for the performance and safety of energetic materials. In order to model the behaviour of these important materials effectively under operational conditions it is essential to obtain detailed structural information at a range of temperatures and pressures.

Nitrogen-rich materials have been considered as the most promising replacement of traditional energetic materials due to the large energy gap between the different nitrogen allotropes as well as the generation of environmental friendly nitrogen gas as the end-product. As a result, methods of synthesizing the nitrogen-rich materials have received increasing attention. Apart from the traditional chemical synthesis, high-pressure technique had been proved an effective tool to create such kinds of materials. However, several issues still existed concerning the high-pressure synthesis of energetic materials. Therefore, searching for precursors is of great interest. Here we report studies of four promising precursors, 5-aminotetrazole, 5-methyltetrazole, 5, 5-b́is(2-methyltetrazolyl)amine monohydrate and cyanuric triazide, under high pressure by Raman and IR spectroscopy, among which 5, 5-b́is(2-methyltetrazolyl)amine monohydrate and cyanuric triazide were also studied using X-ray diffraction. Besides, the high-pressure behavior of s-triazine was also investigated to have an in-depth understanding of the properties of cyanuric triazide. In chapter 2, 5-aminotetrazole and 5-methyltetrazole were investigated and compared to examine the pressure effects on the ring structures and the high-pressure behaviors. No phase transitions for 5-aminotetrazole were found in the whole pressure range. However, four phase transitions were observed for 5-methyltetrazole, evidenced by the by the appearance of new lattice modes, the changes in peak profile as well as the pressure dependence of Raman lattice modes over different pressure ranges. Upon decompression, the tetrazole ring vibration modes in both compounds were fully recovered, suggesting the high stability of the tetrazole ring. The Raman and IR spectroscopic data together allowed for the analysis of the possible reasons of the stability of the tetrazole ring. In chapter 3, another tetrazole derivative, 5, 5-b́is(2-methyltetrazolyl)amine monohydrate, was investigated by vibrational spectroscopy and X-ray diffraction. The Raman and IR spectroscopic data together with the XRD patterns collectively suggested there were no phase transitions in the entire investigated pressure range. Several changes were observed during compression and possible mechanisms were proposed. Upon decompression, all the Raman and IR modes were completely recovered, indicating the reversibility and good stability of this material. Chapter 4 focuses on the high-pressure studies of two six-member aromatic rings, s-triazine and cyanuric triazide. A total of four phase transitions for s-triazine were observed, evidenced by changes in peak profile, the number of vibrational modes, as well as the pressure dependence of Raman lattice modes over different pressure ranges. The transition was identified irreversible for the lattice modes were not recovered upon decompression. In addition, a ring-opening reaction took place, suggested by the recovered Raman and IR internal modes. For cyanuric triazide, no phase transitions were observed in the pressure range of 0-26 GPa and one chemical reaction above 26 GPa. In addition, the transition was partially irreversible evidenced by the different Raman profiles in different parts of the sample. Possible reaction mechanisms were proposed accordingly.

Overall research objectives were: to study energetic materials of interest to the Navy/DoD at the high-pressure and high-temperature of detonation; to study the initiation mechanism of detonation; to learn the phase, lattice, and molecular symmetry, and measure theoretical maximum density (TMD) of a material at high pressure and temperature just before initiation; to understand exactly what chemical bonds are most energetic and why, at the pressure and temperature of detonation; to model the global kinetics and reaction mechanism of energetic materials during detonative reactions.
