Abstract
The quality and internal microstructure of crystals have a great influence on the sensitivity of energetic materials. Moreover, their particle size and particle size distribution are of great importance to processing technology. Particle properties can especially be influenced by applying different crystallisation techniques, such as cooling crystallisation, membrane crystallisation, emulsion crystallisation, etc. The goal of the investigation reported was to determine the interrelationship between the properties of grown crystals and process parameters. Special attention was directed to the qualitative and quantitative examination of crystal defects and their dependence on the experimental conditions. The morphology and structure of crystals were calculated by molecular modelling. The effect of crystal defects on the sensitivity of the material was tested on different collectives of particles with varying amount of crystal defects.
