The feasibility of continuously producing spherical ammonium dinitramide particles (ADN-prills) in microfluidic droplet generators was proven. This new technique promises benefits related to size and dispersity control of the prills and it opens new possibilities to explore the influence of additives on the properties of ADN. Further it can minimize the thermal decomposition of ADN during the prilling process by heating up just small amounts which are used immediately for the process. Microfluidic droplet generators using parallelized microchannels offer the potential of scaling-up the process.
