Reverse micelles of oxyethylated nonylphenol (Triton N-42) were used to synthesize ultradispersed powder of ammonium nitrate with the yield 75% and content 79%. Its composition and morphology were examined by colorimetry, IR Fourier spectroscopy, scanning electron microscopy (SEM) and X-ray diffraction analysis (XRD). According to XRD, the sample is stable with time, although it is a mixture of three polymorphic forms of crystal ammonium nitrate - one stable and three metastable forms. The agglomerates consists of 20-50 nm nanoparticles; a part of nanoparticles form filaments of length 0.5-1.5 μm and thickness 25-30 nm, as estimated by SEM.
