METHOD FOR TREATMENT OF EXPLOSIVE SUBSTANCE Russian patent published in 2016 - IPC C06B21/00 C06B45/18 

FIELD: blasting operations.

SUBSTANCE: invention relates to technology of composite explosive substances (ES) and can be used in detonating charges, lighters, detonators and other explosive devices. Method for explosive substance processing involves obtaining suspension of explosive substance or its mixture with powder of metal in liquid dispersion medium to produce metal film on surface of crystals of explosive substance. Dispersion medium used is presented by metal gallium or its alloys, and mixing is carried out at temperature of not less than 40 °C, but not higher than melting point of explosive substance from class of nitramines or nitroesters. Fraction of liquid gallium or its alloy is from 2 to 50 % of total volume of suspension mix. Explosive substance can contain metal powders of aluminium, zirconium, titanium, tantalum and tungsten.

EFFECT: method provides reduced sensitivity to mechanical action of ES, lower toxicity, protection against oxidation of metal particles contained in ES, as well as homogeneity of compositions and fewer process operations in preparation process.
