For all three explosives it was found that the initiation pressure strongly increases with the loading density ρ, showing a linear dependence in semi logarithmic coordinates log(P_i) - ρ, indicating exponential decrease of the explosive shock sensitivity with the rise of loading density. From ...
In some cases it is advantageous to add a self-explosive ingredient such as particulate trinitrotoluene (TNT), pentaerythritol tetranitrate (PETN) or smokeless power to further improve the sensitivity or strength or both of the slurry explosives and thereby ensure detonation and propagation. (12 ...
the synthesis of these well-known HEDMs are significant breakthroughs in the field of energetic materials, the majority of them face similar problems, such as complex synthetic routes, high production costs and poor molecular stabilities (e.g., hydrolysis or high sensitivity). Therefore, a long-...
Finding new high-energy-density materials with desired properties has been intensely-pursued in recent decades. However, the contradictory relationship between high energy and low mechanical sensitivity makes the innovation of insensitive high-energy-density materials an enormous challenge. Here, we show h...
cyclo-N5− salt Fused tricyclic Low sensitivity High density 1. Introduction Polynitrogen compounds are promising environment-friendly high energy materials with immense application potential as propellants and explosives.1,2 As a carbon-free member of the azole series, the pentazolate anion (cyclo-...
Nitro and fluoro groups, among others, have become viable substituents on the triazole framework because of their particular contribution to detonation properties and moderate sensitivity. In this study, Density Function Theory (DFT) approach was employed to design fluorinated bis(trinitromethyl) azo ...
This explains why superior detonation performances are usually accompanied by high sensitivities and low stability. From a practical point of view, acceptable sensitivity and stability are important factors to be considered when developing new energetic materials. [20], [21], [22], [23] During the...
Barbiturates I and II are stable towards an impact sensitivity test, when a weight of 2 kg mass hammer is dropped from a height of 160 cm of the instrument. TGA/DTA analyses at four different heating rates (5, 10, 20, and 40 K/min) imply that they undergo exothermic decomposition (...
The solubility of the polymer precursors in TMETN also reduces the energetic liquid's sensitivity. The latent cure catalyst Dabco T-131 is used to minimize shrinkage associated with thermal expansion. The exact formulation is described herein under the heading “Experiments”. A cylindrical shape ...
