| abstract |
The invention relates to a desensitisation method that involves coating crystals of an explosive energy substance, wherein said method comprises depositing, in a fluid and not in normal temperature and pressure conditions, preferably in supercritical conditions, a metal and/or polymer film, advantageously a metal film or a polymer film at the surface of said crystals, wherein the metal(s) and/or polymer(s) used have been previously dissolved in a solvent. The invention also relates to coated crystals of an explosive energy substance that can be obtained by said method, and to energy materials containing said coated crystals and/or crystals desensitised by said method. |
