A method for producing substantially spherical energetic compounds such as ammonium dinitramide (ADN) which minimizes the time during which the ADN is melted involves providing solid ADN, feeding the ADN at a controlled continuous rate to a heating means, melting the ADN, the melted ADN being fed continuously to a non-solvent cooling fluid maintained at a temperature below the temperature of solidification of the ADN, the cooling fluid agitated in a manner which promotes theformation of droplets of controlled size which solidify in the cooling fluid to produce substantially spherical ammonium dinitramide in a particle size corresponding to the droplet size.

[ What is claimed is:] [1.] A method for producing a substantially spherical energetic compound comprising:providing a solid energetic compound;feeding the solid energetic compound in a rate controlled continuous stream to a heating means;melting the energetic compound in the heating means;providing a non-solvent cooling liquid maintained at a temperature below the solidification temperature of the energetic compound;adding the melted energetic compound at a rate which corresponds substantially to the solid feed rate into the cooling liquid; and,controllably agitating the cooling liquid to disperse the melted energetic material into droplets of controlled size; such that the droplets are solidified in the cooling liquid into substantially spherical particles, the particles size corresponding to the droplet size.
