Practical Approach Book
Short Description
Depending on the particle type, explosives have varying detonation powers in practical use. Particle technology is therefore an integral part of energetic materials design, and the existing gap in literature coverage is now filled in by this book. Each chapter describes the fundamentals of each process with emphasis on aspects particular to explosives, expanding agents and propellants. The book is therefore equally of interest for chemists, physicists, materials scientists, chemical and process engineers as well as scientific personnel in military capacities.

Incorporation of particular components with specialized properties allows one to tailor the end product's properties. For instance, the sensitivity, burning behavior, thermal or mechanical properties or stability of energetic materials can be affected and even controllably varied through incorporation of such ingredients. This book examines particle technologies as applied to energetic materials such as propellants and explosives, thus filling a void in the literature on this subject.
Following an introduction covering general features of energetic materials, the first section of this book describes methods of manufacturing particulate energetic materials, including size reduction, crystallization, atomization, particle formation using supercritical fluids and microencapsulation, agglomeration phenomena, special considerations in mixing explosive particles and the production of nanoparticles. The second section discusses the characterization of particulate materials. Techniques and methods such as particle size analysis, morphology elucidation and the determination of chemical and thermal properties are presented. The wettability of powders and rheological behavior of suspensions and solids are also considered. Furthermore, methods of determining the performance of particular energetic materials are described.
Each chapter deals with fundamentals and application possibilities of the various methods presented, with particular emphasis on issues applicable to particulate energetic materials. The book is thus equally relevant for chemists, physicists, material scientists, chemical and mechanical engineers and anyone interested or engaged in particle processing and characterization technologies.

E-STREAMS
Nach seinem Maschinenbau-Studium an der RWTH Aachen setzte Ulrich Teipel seine wissenschaftliche Laufbahn 1991 im ICT mit Arbeiten zur mechanischen Verfahrenstechnik fort, promovierte extern an der Universität Bayreuth und wurde 1996 zum stellvertretenden Leiter der Abteilung "Energetische Materialien" des Fraunhofer ICT berufen. Er hat dort insbesondere die Partikeltechnologie ausgebaut und sich einen hervorragenden Ruf in der mechanischen Verfahrenstechnik erarbeitet, unter anderem auch durch die Begründung der ICT-Kongressreihe "Partikeltechnologie". Er wird dem Fraunhofer ICT im Rahmen einer vertraglich vereinbarten Zusammenarbeit weiterhin eng verbunden bleiben und dort die entsprechenden wissenschaftlichen Arbeiten betreuen.
