Book excerpt: The application of complex networks of elementary chemical reactions to the gas phase of burning energetic materials has increased markedly over the last decade. The exquisite complexity of these gas-phase reaction networks, coupled with available high-rigor treatments of transport, is not matched by an equivalent level of sophistication in descriptions of the condensed-phase and interfacial phenomena. Owing to the bastly more complicated, many-body nature of the condensed phase, this condition is not likely to be relieved soon. In response to these difficulties, a new semi-empirical approach to burning-rate calculation has been developed and applied to frozen ozone, cyclotrimethylenetrinitramine (RDX), and nitroglycerine. The new approach hypothesizes a single overall reaction linking the unreacted material to the net products of condensed-phase decomposition and characterizes their rate of formation according to an empirically derived pyrolysis law. These condensed-phase products become the reactants for the gas phase, which are treated in full elementary-reaction detail. Using this new semi-emperical model, a methodology for computing the relative effects of several additives on the burning rate of nitroglycerine is developed and demonstrated. Hopefully this approach will enable more rapid progress in modeling multi-ingredient propellants than did previous approaches attempting to model the condensed-phase processes in detail.

Book excerpt: This book offers a comprehensive account of energetic materials, including their synthesis, computational modeling, applications, associated degradation mechanisms, environmental consequences and fate and transport. This multi-author contributed volume describes how armed forces around the world are moving their attention from legacy explosive compounds, which are heat and shock sensitive (thus posing greater challenges in terms of handling and storage), to the insensitive munitions compounds/formulations such as insensitive munitions explosive (IMX) and the Picatinny Arsenal Explosive (PAX) series of compounds. The description of energetic materials focuses on explosives, pyrotechnic compositions, and propellants. The contributors go on to explain how modern generation energetic compounds must be insensitive to shock and heat but at the same time yield more energy upon explosion. Nanoinspired and/or co-crystallized energetic materials offer another route to generate next-generation energetic materials, and this authoritative book bridges a large gap in the literature by providing a comprehensive analysis of these compounds. Additionally, it includes a valuable overview of energetic materials, a detailed discussion of recent advances on future energetic compounds, nanotechnology in energetic materials, environmental contamination and toxicity, assessment of munitions lethality, the application quantitative structure–activity relationship (QSAR) in design of energetics and the fate and transport of munition compounds in the environment.

Book excerpt: This unique book investigates the synthesis, kinetics, and thermal decomposition properties and processing of energy-producing materials used in propellants, explosives, pyrotechnic, and gas-generating compositions. Thermal Decomposition and Combustion of Explosives and Propellants provides several mechanisms and stages for the thermal decomposition and combustion reactions of most flammable compounds and their mixtures, such asaliphatic and aromatic nitrocompounds, nitramines, nitroesters, organic azides, furazanes, tetrazols, difluoroamines, polynitrous heterocycles, and onium salts. The authors examine the classic problem of the dependence of explosive activity on molecular structure, using applications to predict the stability, compatibility, and the stabilization of explosives and propellant components. They also offer experimental results examining factors such as subsurface decomposition, evaporation, and dispersion of materials, which can be used to control combustion of condensed systems. Providing several approaches to stability, safety, and controlled combustion of flammable substances, Thermal Decomposition and Combustion of Explosives and Propellants is a multi-dimensional resource for graduate students, researchers and professionals interested in chemical kinetics, the combustion and synthesis of high-energy materials, criminal forensics, and the field of explosives, powders, and solid rocket propellants.

Available in PDF, EPUB and Kindle. Book excerpt: Incorporation of particular components with specialized properties allows one to tailor the end product's properties. For instance, the sensitivity, burning behavior, thermal or mechanical properties or stability of energetic materials can be affected and even controllably varied through incorporation of such ingredients. This book examines particle technologies as applied to energetic materials such as propellants and explosives, thus filling a void in the literature on this subject. Following an introduction covering general features of energetic materials, the first section of this book describes methods of manufacturing particulate energetic materials, including size reduction, crystallization, atomization, particle formation using supercritical fluids and microencapsulation, agglomeration phenomena, special considerations in mixing explosive particles and the production of nanoparticles. The second section discusses the characterization of particulate materials. Techniques and methods such as particle size analysis, morphology elucidation and the determination of chemical and thermal properties are presented. The wettability of powders and rheological behavior of suspensions and solids are also considered. Furthermore, methods of determining the performance of particular energetic materials are described. Each chapter deals with fundamentals and application possibilities of the various methods presented, with particular emphasis on issues applicable to particulate energetic materials. The book is thus equally relevant for chemists, physicists, material scientists, chemical and mechanical engineers and anyone interested or engaged in particle processing and characterization technologies.

Book excerpt: This book represents a collection of lectures presented at the NATO Advanced study Institute(ASI) on "Chemistry & Physics of the Molecular Processes in Energetic Materials", held at Hotel Torre Normanna, Altavilla Milicia, Sicily, Italy, September 3 to 15, 1989. The institute was attended by seventy participants including twenty lecturers, drawn from thirteen countries. The purpose of the institute was to review the major ad vances made in recent years in the theoretical and experi mental aspects of explosives and propellants. In accordance with the format of the NATO ASI, it was arranged to have a relatively small number of speakers to present in depth, re view type lectures emphasizing the basic research aspects of the subject, over a two week period. Most of the speakers gave two lectures, each in excess of one hour with addition al time for discussions. The scope of the meeting was limit ed to molecular and spectroscopic studies since the hydro dynamic aspects of detonation and various performance crite ria of energetic materials are often covered adequately in other international meetings. An attempt was made to have a coherent presentation of various theoretical, computational and spectroscopic approaches to help a better understanding of energetic materials from a molecular point of view. The progress already made in these areas is such that structure property (e. g.
