Classification of Explosive Materials

2022
The main focus of this chapter is on the chemical data of primary and secondary explosives. For this 4th edition the data has been up-dated using recent publications and databases. For primary explosives the chemical data on mercury fulminate, lead styphnate, tetrazene, lead and silver azide is presented and for secondary explosives the chemical data ...

Explosively driven fragmentation of granular materials

The European Physical Journal E, 2013
This paper investigates the explosively driven dynamics of dry and wet sand. Contrary to popular belief, wet sand under high strain rate loadings (10(4)s(-1)) is observed to have reduced resistance against flow compared to the dry sand, which is supported by a noticeably enhanced expansion before the breakup followed by an increased number of fragments.

Temperature Change of Light Induced Explosion of explosive material

Propellants, Explosives, Pyrotechnics, 1987
AbstractA theoretical analysis based on the adiabatic consideration of one‐ dimensional model for initiation of explosive materials by intense light is performed. An expression is obtained which can be used to calculate the explosion temperature.

Identification of explosive materials

Forensic Science International, 1990
Abstract Efficient methods and procedures have been worked out allowing to identify both military and non-military (mining, pyrotechnic) explosives. Physical and chemical stability of traces including effects of external influences and various background materials affecting traces have been investigated. Colour tests and procedures for identification

Nanometer functional materials from explosives

SPIE Proceedings, 2009
ABSTRACT The growth of Li 1+x Mn 2 O 4 via detonation reaction was investigated with re spect to the presence of energetic precursors, such as the metallic nitrates and the degree of confinement of the explosive charge. The detonation products were characterized by scanning electron microscopy.

Vapour sensing of explosive materials

Analytical Methods, 2015
The ability to accurately and reliably detect the presence of explosives is critical in many civilian and military environments, and this is often achieved through the sensing of the vapour emitted by the explosive material. This review summarises established and recently developed detection techniques.

Desensitization of Explosive Materials

1976
Abstract : The objective of our work is to determine the generality of an observation that substitution of fluorine for hydrogen in an explosive material leads to desensitization. Substitution of the -CH2- group in FEFO, (FC(NO2) 2CH2O)2CH2, with a -CF2- group to give DFF, (FC(NO2)2CH2O)2CF2, reduces the sensitivity to impact and low velocity ...

Terahertz spectroscopy of explosive materials

SPIE Proceedings, 2004
The terahertz spectrum of the explosive RDX has been measured using a conventional Fourier transform infrared spectroscopy and by terahertz pulse spectroscopy in transmission and reflection modes. Seven absorption features in the spectral range 5-120 cm-1 have been observed and identified as the fingerprints of RDX explosive.

Explosive Fabrication of Composite Materials

Nature, 1968
FIBRE or filament reinforcement of metals is usually carried out by the conventional processes of hot rolling, vacuum infiltration or diffusion bonding of the reinforcement with the matrix metal1. There is a danger that the high temperature attained in such processes, if maintained for a long time, will cause a reaction between matrix and reinforcement
