Abstract
The article deals with the study of the porous ammonium nitrate granules’ (PAN) nanoporous structure of surface and surface layers. The research results, presented in the article, show that the suggested way to generate PAN allows to provide the granule porous structure without destruction of core and disposal of air from the granules. Analysis of experiments results has shown that various types of humidifiers can form various kinds of pores after drying – “mechanical” pores and “modification” pores. Various types of humidifiers have significant effect on the ratio of values of “mechanical” and “modification” pores. The obtained results allow to select the optimal humidifier composition, which promotes the formation of significant amount of macropores on surface and mesopores of near-surface areas.
