Detonability of Ammonium Nitrate and Mixtures on Its Base

Quantities of improvised explosive devices on a base of industrial explosives that were applied at criminal incidents or were withdrawn from illegal circulation were reduced on average on 9% during last decade. This tendency is explained in particular by toughening of control under circulation of commercial explosive devices. The most commonly used improvised explosives according to returns of The Forensic Science Center of Ministry of Internal Affairs are mixtures on a base of ammonium nitrate with organic fuels and aluminum powder. Quantitative and qualitative compositions of such improvised mixtures can be various. The most essential question for a criminal case investigator is argument that excepted substance is explosive one. In this connection detonability of the mixtures on base fne (particle size was near 20 microns) and granulated ammonium nitrate with some organic fuels and aluminum powder was experimentally investigated. Failure detonation diameters of systems were measured experimentally.
