Detonation Characteristics of Light-Initiated Explosive Silver Acetylide-Silver Nitrate

To investigate the feasibility of applying the light-initiated explosive, silver acetylide-silver nitrate (SASN), as an effective simulation of a cold X-ray blow-off event, we carried out experimental researches on the detonation property of SASN ignited by a light flash.First we presented the basic and sensitivity characteristics of SASN, and then based on the analysis of its light-initiated mechanisms, we succeeded in igniting a large area of SASN sprayed layer by a light flash with high voltage, and conducted tests on the detonation characteristics of SASN sprayed layer initiated by light.The results indicate that SASN is a relatively safe agent of light-sensitive explosive with a relatively low detonation velocity of sprayed layer capable of providing low impulsive loads.The test results confirmed that the specific impulse of explosion from SASN is almost linear to the areal density of sprayed layer under the conditions of low-level density.
