High bulk density bicyclo-HMX and RDX crystal materials for use in plastic explosives, PBX and propellants

摘要

To obtain high filling level of solids in plastic explosives, crystal materials were prepared by special crystallization technique. During continual addition of antisolvent to a solution of energetic material surface-active agent Tween 20 was continually added. This procedure gave wide range of crystals (0.05-0.7 mm) having high bulk density (1.1-1.22 g.cm~(-3)). Tween 20 improves shape of crystals too. Obtained bicyclo-HMX is significantly less impact sensitive than starting material. Crystallized RDX and bicyclo-HMX were tested as a component of plastic explosives. High filling level of crystalline explosive (90-93%) was achieved.
