Abstract
A method of preparing organic or inorganic nanoparticles is useful in the manufacture of of fertilizers, pharmaceutical or phytopharmaceutical active ingredients, or insensitive energy materials. The method includes preparing a solution of a compound in a solvent, heating the solution under a pressure ranging from 3 to 300 bars at a temperature higher than the boiling point of the solvent, atomizing the solution in an spray drying chamber using at least one dispersion device and at an angle ranging from 30 to 150° under pressure ranging from 0.0001 to 2 bars, separating the solvent in gaseous form, and recovering the nanoparticles.
