Electrospray: A simple technique to create nanosized RDX
conference paper
The sensitivity of an energetic compound is related to the crystal product quality of that material: internal defects such as inclusions can lead to unwanted initiation. Nano- and submicron sized crystals are too small to contain inclusions and therefore might be less sensitive. With a technique called electrospray crystallization nano- and submicron sized crystalline energetic materials were produced, which are expected to be less sensitive since smaller crystals have less inclusions and crystal defects. The electrospray crystallization method works properly with RDX/acetone solutions. Different solute concentrations, geometrical configurations and voltage conditions were studied, and 500 nm sized RDX particles with a narrow size distribution were produced. With this submicron sized product impact tests and shock test will be carried out to check the expected reduced sensitivity.
