ADN (ammonium dinitramide) is the promising oxidiser which is expected to be applied e.g. in solid rocket propellants. The manufacturing of ADN prills (spherical ADN particles) with useful morphology and reproducible quality is realised by means of the emulsion crystallisation process. The yet remaining drawback of ADN is the less compatibility with common curing agents used in most binder systems. This incompatibility should be overcome by coating the ADN particles. For this purpose the fluidised bed technology was established at ICT (Fraunhofer-Institut Chemische Technologie, Institute Chemical Technology). Nowadays two coating equipments (lab-scale and field-scale) are available, both modified for the processing of hygroscopic and explosive materials. Different polymeric coating materials have been tested and turned out to be suitable for application in the fluidised bed. The properties of the coated ADN particles have been characterised by microscopy, particle size investigation, specific surface area measurement and a very special measuring instrument, which allows detecting the crushing strength of individual particles. It is to be seen that the ADN prills can be coated separately and with uniformly thin layers. It has also been verified that the mechanical stability of particles can be increased by coating them. The compatibility of coated and uncoated ADN prills and isocyanate containing binder systems was investigated by microcalorimetric measurements and vacuum stability tests. It was proved that the compatibility could be increased by coating the ADN prills with polyacrylates, HTPB (hydroxy-terminated polybutadiene) or GAP (glycidyl azide polymer).
