Study on Preparation and Properties of RDX/Al Superfine Composite

YANG Yi, XU Jian hua, LUO Fu sheng (Superfine Powder Technolgy, Institute of Nanjing University of Sci. & Tech., Nanjing 210094, China)  
To research the influence of superfining and compounding on the properties of the explosive, the RDX/Al superfine composite powders are prepared in YLG model stirring grinding machine. The composite powders prepared in different grinding media (water and alcohol) are compared and studied. The composite particles are studied on their diameters, particle appearances, properties of thermodynamics, particle compositions and explosive heat, using particle diameter sizer, SEM, DSC, XRD and explosive heat testing machine respectively. The study results indicate that the water grinding media may contribute to the compounding of particles, while the superfining and dispersing of particles is attributed to the alcohol grinding media. And the coming into being of energetic (C 2H 5O) 3Al improves the explosive heat of sample grinding in alcohol. To explain the phenomena, models on the superfining and compounding of particles and the thermolysis of superfine RDX/Al composite explosive are formed. And the models are well in accord with the experiment results.
