Abstract
The results of a study on the development of a method for coding explosives are presented. As coding additives (CAs), it is proposed to use aluminum alloy powders with dosed amounts of rare-earth coding elements (CEs). This choice is dictated by the fact that aluminum alloys are commonly used as efficient additives in explosive compositions, while rare-earth elements are used as additives in technological operations, but are absent in the composition of standard explosives. In this case, the key to information on a given explosive and its manufacturer is the ratio of CE concentrations determined when analyzing explosives, e.g., when investigating an act of terrorism. Examples of explosion product decoding using a LIES laser-spark express analyzer.
