Book Review: Initiation of Explosives & Pyrotechnic Materials

Posted on November 14, 2009 · Leave a Comment
 

By: Jean-Rene Duguet – R&D Manager and Consultant in Pyrotechnics.
Preface by: Dr Attie Goosen
Published by: Cultures et Techniquescultures.techniques@hotmail.fr
ISBN: 978-2-918209-02-7
Price: 50Euros

This small paperback book is packed with information on the chemistry and mechanics of initiation and has extensive chapters on:-

  • General outline
  • Explosives and Production Processes
  • Initaitors and Related Devices
  • Metrology and Safety

There is extensive detail of the physical characteristics of initiating substances, together with formulations and a good section on sensitivity of various initiating explosives.  However the book is somewhat frustrating in so much that the scale and clarity of diagrams and images varies widely, and chemical formulae are inconsistently portrayed.  It is also expensive for a 221page paperback (50 Euros) and I felt that I could have certainly lived with a smaller and more consistent typeface throughout if it left more room for bigger diagrams or had reduced the size and price of the book as a result.

Nevertheless I would recommend this book for the bookshelves of practitioners in almost any area of pyrotechnics and explosives – initiation is often poorly understood, and this book does much to inform the reader in this most important subject.

Performance Comparison between Old and New Obron German Dark Aluminum

Posted on May 21, 2009 · 1 Comment
 

K. L. and B. J. Kosanke

ABSTRACT: In 1997, Obron Atlantic changed their Ger-man dark aluminum. (Their former product number was 5413; the new product was designated 5413 H Super.) We had published the results of a series of sound output tests of various salute powders, which included the effect of using various aluminums, including Obron’s old German dark. Because of our past work, and in response to a query on the Internet, we decided to conduct a brief investigation comparing the sound output of these two aluminum powders when used in a common flash powder formulation. This article presents those results.

ATF’s Classification of Flash Powders

Posted on May 21, 2009 · Leave a Comment
 

K. L. Kosanke

ABSTRACT:  This brief article is based on my comments to the US Bureau of Alcohol, Tobacco and Firearms (ATF) concerning their classification of all flash powders as high explosives. In this query, I chose not raise the issues of flash powder storage requirements, quantity limits in process buildings, or any of the issues regarding bulk salutes. I omitted those subjects because I was not prepared to make specific recommendations on those subjects at this time. This article was written for publication because of the possibility someone would find this information useful or interesting.

Burn Rates of Clusters of Gold Sparklers

Posted on May 21, 2009 · 1 Comment
 

K. L. and B. J. Kosanke

ABSTRACT: In recent years, it has become generally known that clusters of sparklers burn substantially faster than individual sparklers. However, little if any quantitative data has been presented in the literature. Toward that end, this brief article presents some data collected a few years ago by the authors.

Theory of Colored Flame Production

Posted on February 10, 2009 · 2 Comments
 

B. E. Douda

Abstract: The theories and attributes associated with the production of colored flames are presented. Particular attention is given to flames containing strontium (red), barium (green), sodium (yellow) and copper (green or blue). Thermal excitation of vaporized neutral atoms, molecules and ions is correlated with the emission of atomic, band and ionic spectra. These spectra are tabulated. The color contribution of C-type chemiluminescence, a non-thermal excitation, is described briefly. The variability of emitters, emissions and color with the operating flame temperature is discussed in relation to the thermodynamic properties of the reactants and the products of combustion. These thermal properties are tabulated. Ionization is shown as a contributor to color degeneration. The use of an ionization buffer to reduce ionization is explained. Depending on flame conditions and the metal being used, the influence of halogens on the production of color is discussed. The influence is not always beneficial. The flame equilibrium shift caused by the halogens is described for each of the metals. Metals and anions other than the halides are discussed in relation to their ability to intensify or suppress emission. The preferred emitters for each of the metals are listed, and idealistic postulates are presented which apply to the production of color in a flame.
