Obtaining granules of porous ammonium nitrate (PAN) as a component of industrial explosives is associated with the lack of reliable methods for controlling the process of nanopore formation.
In this work, the studies of the formation process of a nanoporous structure, begun in [1–3], are continued. The assessment of the quality of the nanoporous structure under various conditions for its preparation was carried out according to the data of microscopic analysis and the determination of the specific properties of PAN as a component of an industrial explosive.
The research results made it possible to determine the degree of influence of various technological indicators of the granulation and dehydration process on the nanoporous structure of PAN granules.

This work was carried out under the project "Technological bases of multistage convective drying in small-sized devices with utilization and heat recovery units," project No. 0120U100476.
