Investigation of RS-RDX Samples from the MSIAC-Round Robin by Means of X-ray Diffraction Rocking Curves

摘要

The microstructure of explosives is in the scope of current research. The interest stems from investigations showing that careful processing of crystalline ingredients reduces the shock sensitivity of plastic-bonded explosives. The mechanisms behind the sensitivity reduction are far from being clear. In this context the NATO Munitions Safety Information Analysis Center (MSIAC) organized a Reduced Sensitivity RDX Round Robin (R4) distributing seven coarse RDX-powders (C_3H_6N_6O_6) to laboratories all over the world [1, 2] These samples have been investigated at FhG-ICT and at Empa by means of X-ray Powder Diffraction Rocking Curves in order to correlate micro-structural parameters with shock sensitivities and to verify whether the method would deliver comparable results from different laboratories.
