Effect of surfactant additives on the size and morphology of ammonium and potassium nitrate particles obtained by crystallization from reverse micellar solutions of tergitol NP-4

Effect of small additives of hydrophilic and hydrophobic surfactants (sodium dodecyl sulfate, cetyltrimethylammonium bromide, Span-80, and AOT) on the size and morphology of particles of ammonium and potassium nitrate powders prepared by isothermal bulk crystallization from reverse micellar solutions of Tergitol NP-4 in decane and diesel fuel was studied. Initial microemulsions were characterized by photon correlation spectroscopy, powders were described by scanning electron microscopy, energy dispersion X-ray analysis, microanalysis, and flame photometry. In the context of increase of powder dispersity, hydrophobic anionic AOT was found to be promising additive, it produces whisker-type particles 5–10 μm long and 0.1–0.5 μm thick.
