Ammonium Nitrate Explosives for Civil Applications

This work describes the science and technology of formulation and manufacturing of non-nitroglycerine explosives with ammonium nitrate
as the main ingredient. Based on the author's industry experience of more than thirty years, it provides an unparalleled treatment of one of
the commercially most important classes of explosives and therefore stimulates further research and development efforts in the field of
explosives for civil applications.

Explosives based on ammonium nitrate can be handled more easily than other explosives because they are more stable and less sensitive to
external stimuli such as pressure, shaking or inadvertent ignition. Consequently, they provide more safety for both the manufacturer and
the end user, making them the explosives of choice for civil applications such as mining, construction and pyrotechnics.

This book is an invaluable addition to the library of any Explosives and Mining Specialist, Pyrotechnician, Materials Scientist, Military
Authority, and Safety Officer.
