Abstract

A technique of Rapid Expansion of Supercritical Solutions (RESS) to produce nano-crystalline energetic materials was developed and characterized in application to production of nano-scale crystals of cyclotrimethylene- trinitramine (RDX). Nano-crystals of RDX were formed by expansion of supercritical solutions of RDX in carbon dioxide through a 100 μm sapphire nozzle at initial pressures of 150 - 295 bar and temperatures of 323 - 363 K. Produced particles were characterized by Field Emission Scanning Electron Microscopy, X-ray diffraction, HPLC, and melting point analysis. The process produced particles with the mean size in the range of 110 - 300 nm with a narrow size distribution.
