Ammonium Nitrate: Use and Misuse

Ammonium nitrate (AN) is commonly present on the world market as fertilizing agent (fertilizer grade) and as main ingredient in explosive formulations (technical grade). The lecture will deal with the explosive properties of ammonium nitrate, both fertilizer and technical grade. An abridged presentation of the basic physical and chemical characteristics of AN will be given. Although being able to detonate, AN is – according to international regulations – classified as oxidizing agent. Nevertheless, AN does possess clear explosive properties and can be considered as a “non‐ideal” explosive. The lecture will focus on two specific topics:

‐ “Normal” use of AN in commercial explosive formulations: Large stockpiles of AN become a major safety concern for all economic actors involved in the production, transport, storage and post‐processing of AN. Risks associated with AN will be highlighted during the lecture.

‐ “Illegal” use of AN: because of its explosive properties and its easy procurement, AN is unfortunately used by offender. In this context, the frontier between fertilizer and technical grades is rather thin.

Stationary-state burning of primary explosives

Aim of this talk is to introduce to the audience an important role of the stationary combustion parameters (burning rate and its dependence on pressure) of individual primary explosives in forming some dependent explosive properties such as acceleration of explosive transformation in the porous charge, initiating efficiency, sensitivity aspects.

It will be touching upon methods of sample preparation and process registration beginning with old researches on mercury fulminate to recent studies on fast-burning complex compounds. A series of experimental burning parameters of primary explosives from different chemical classes will be given, and influence on the initiation efficiency will be illustrated by the example of acetone peroxides.
