THE RESPONSE OF NITROGUANIDINE TO A STRONG SHOCK
Abstract
In its range of detonability, nitroguanidine (NQ) behaves as a Group 1 explosive. In addition, it exhibits failure at the high TMD as well as the more common failure at a lower critical density. The high bulk density (HBD) form of NQ exhibits a critical diameter about three times that of the low bulk density form. This fact aided in studying the subcritical region of NQ (HBD) where a strong shock produces a subdetonation, supersonic, constant velocity front. This pseudo-detonation or LVD had failure characteristics similar to the detonability limits of Group 2 materials. That trend, the power of the LVD reactions, and the dimensions of the various gap tests can be combined to explain (1) a hump in the curve 50% pressure vs % TMD obtained for NQ(HBD) in the gap test and (2) a reversal in apparent shock sensitivity rating of NQ(HBD) and NQ(LBD) when tested on the large- and small-scale gap tests.
