Production of desensitized, ultrafine PETN powder

Powder Technology, 2022
Abstract Pentaerythritol tetranitrate (PETN) is a widely studied high explosive (HE), most commonly used in detonator applications. In this work, we use a spray drying technique to manufacture a new “nano-powder” morphology of PETN. The spray dried PETN is several orders of magnitude smaller in particle size than traditionally prepared PETN powders ...

Polynitramino compounds outperform PETN

Chem. Commun., 2010
New polynitramino compounds were synthesized and fully characterized using IR and multinuclear ((1)H, (13)C, (15)N) NMR spectroscopy, and elemental analysis as well as single-crystal X-ray diffraction.

PETN Ignition Experiments and Models

The Journal of Physical Chemistry A, 2010
Ignition experiments from various sources, including our own laboratory, have been used to develop a simple ignition model for pentaerythritol tetranitrate (PETN). The experiments consist of differential thermal analysis, thermogravimetric analysis, differential scanning calorimetry, beaker tests, one-dimensional time to explosion tests, Sandia's ...

Laser initiation of PETN

Combustion, Explosion, and Shock Waves, 1996
We studied experimentally the initiation ofPETN with a dispersity of 3700–22,000cm 2/kg and a density of 0.6–1.3g/cm 3 by a laser (λ=1.06 µm and τ=40nsec). Data processing was based on dimensional analysis of the process and study of the phenomena accompanying initiation (crater formation and sudden change in optical characteristics).

PETN-Forschung 1993–2003

2004
Die PETN-Forschung hat naturgemas nicht erst im Jahre 1993 begonnen. Beginnend mit dem Jahr 1993 kam es aber aus verschiedenen Grunden zu einer Renaissance der PETN-Forschung. Zunachst einmal war es wichtig, das vorhandene Datenmaterial zusammenzustellen und einem bewertendem Review zu unterziehen. Das von Noack 1992 [1] zusammengestellte und bewertete
