This paper presents an overview of methods for recrystallizing 3-nitro- 1,2,4-triazol-5-one (NTO), with particular emphasis on methods for obtaining spheroidal particles with low porosity. The effects of selected solvents and surfactants on the recrystallization results was checked. Products in the form of spheroidal particles were obtained for some selected solvent-surfactant systems. The bulk density, surface area, size distribution, and sensitivity to friction and impact were tested for the spherical NTO samples and thermal analysis was also performed.
