Waste explosives and other hazardous materials--hazard potential and remedial measures: an overview.
A large amount of energetic materials including propellants, high explosives, pyrotechnics are subjected to disposal either due to expiry of their useful life or rejection in the manufacturing process. The environmental regulations do not allow the hazardous materials for open burning / detonation in view of the health hazard involved in these operations. The present paper describes the hazard ...
Deterrents are materials that use in gun propellant formulations as controlling initial burning rate and to prevent of high chamber pressures in the interior ballistic. However, traditional deterrents are highly toxic and suspected carcinogen which makes them chemicals of concern that are non-energetic inert compound and reduce total chemical energy of propellant and reduce final performance of...
N-Nitramino/N-oxyl functionalization strategies were employed to investigate structure-property relationships of energetic materials. Based on single-crystal diffraction data, π-π stacking of pyrazole backbones can be tailored effectively by energetic functionalities, thereby resulting in diversified energetic compounds. Among them, hydroxylammonium 4-amino-3,5-dinitro-1H-pyrazol-1-olate and di...
The equation of state (EoS) is the relation between physical quantities describing thermodynamic states of materials under a given set of conditions such as pressure, temperature, and volume. The EoS plays a significant role in determining the characteristics of energetic materials, including Chapman–Jouguet point and detonation velocity. Furthermore, the EoS is the key to connect microscopic a...
prepared for the IMA Workshop on High-Speed Combustion in Gaseous and Condensed Phase Energetic Materials, Minneapolis, November 8–12, 1999
Within the field of materials science, high-nitrogen compounds represent an important class of energetic materials. As a result of the existence of a large number of inherently energetic N N or N=N bonds within the molecules, highnitrogen compounds possess very high positive heats of formation, thereby making them intrinsically high-energy materials. The energy of most compounds with high-nitro...
Energetic materials store a large amount of chemical energy that can be readily converted into mechanical energy via decomposition. A number of different ignition processes such as sparks, shocks, heat, or arcs can initiate the excited electronic state decomposition of energetic materials. Experiments have demonstrated the essential role of excited electronic state decomposition in the energy c...
This review discusses the recent advances in the syntheses of high explosive energetic materials. Syntheses of some relevant modern primary explosives and secondary high explosives, and the sensitivities and properties of these molecules are provided. In addition to the synthesis of such materials, processing improvement and formulating aspects using these ingredients, where applicable, are dis...
