Empirical methods for calculating parameters of ideal and imperfect detonation of explosive compositions of various types, density of single crystals and detonation speed of individual explosives, as well as characteristics of impact compression of explosives and explosive solutions are considered. Detailed examples of calculation are given. Most of the methods described were developed by the authors at the Department of Chemistry and Technology of Organic Nitrogen Compounds of the St. Petersburg State Technological Institute (Technical University) and at the SKTB "Technologist." The book is intended for researchers and specialists involved in the development of explosive compositions for various purposes and their use in various fields. In addition, it can be useful for training specialists in the specialty "Chemical technology of energy-saturated materials and products," as well as graduate students in the specialty "Chemical technology of fuel and high-energy substances."
