Experimental determination of detonation parameters of explosives based on ammonium nitrate

Laser interferometer VISAR was used for investigation of the reaction zone structure and determination of detonation parameters in two different kinds of explosives based on ammonium nitrate: emulsion explosives and composite explosives with plastic binder. The influence of ammonium particles size, structure and charge diameter on detonation velocity and distribution of parameters inside of the reaction zone has been investigated for composite explosives. The effect of aging time of emulsion matrix with different storage time was found.
