The article deals with the study of phase composition and crystal nanoporous structure of core and surface layer of porous ammonium nitrate (PAN). The research results, presented in the article, show that the proposed way to generate PAN allows to provide the granule porous structure without changing of its phase composition. The crystal structure of granules after the humidification and heat treatment has some changes due to the increase of the number of pores. The change of crystal structure, in turn, allows to open access to nanopores that are located in the volume of granules. This allows to increase the holding capacity indicator of granules. An important result of conducted researches is the establishment of the fact of oxygen molecules “integration” to the crystal lattice of ammonium nitrate, which have positive impact on the industrial explosives detonation velocity.
