| description | The invention relates to a method for preparing spherical ammonium dinitramide (ADN) particles based on confinement micro-droplets of a microchannel, the ammonium dinitramide (ADN) particles prepared by the method and application of the ammonium dinitramide (ADN) particles. The method comprises the following steps: firstly, preparing an ADN solution, selecting a proper anti-solvent, then enabling the ADN solution and the anti-solvent to pass through a coaxial microchannel reactor at a certain flow rate to form ADN solution-anti-solvent micro-droplets, dispersing the micro-droplets in a specific solvent, carrying out ultrasonic or stirring to obtain an ADN spherical particle suspension, and finally, carrying out suction filtration, washing and vacuum drying, to obtain the spherical ADN particles. The micro-channel reactor is adopted, the particle size of the spherical ADN particles can be adjusted according to the diameter ratio of the micro-channel and the flow rate ratio of the solution to the anti-solvent, |
