Ammonium dinitramide (ADN) is the upcoming oxidizer for solid propellants. Spherical AND particles, so-called ADN-prills, are a key product for the development of environmental friendly and low-signature solid propellants for defense and space applications. The particle size and the spherical shape of the ADN-prills can be controlled by the emulsion crystallization process or by spray congealing processes. In this work the microstructure of ADN-Prills was investigated by 2D-X-raydiffraction. This leads to a more profound knowledge about the crystal structure of ADN-prills and gives the opportunity to produce enhanced ADN particles for propellant applications.
