Investigation of 3D Nanoporous Structure Formation Process Controlling Mechanisms on the Surface and Inside the Granule of Ammonium Nitrate

The article deals with theoretical justification and experimental confirmation of possibility to control the granules nanoporous structure formation process in the vortex gas flow. Theoretical bases of the granule nanoporous structure are demonstrated. Some mechanisms to control the process of the nanopores developed net formation on the surface of the granule and inside it are proposed in the work. The structure of porous ammonium nitrate granule with a net of nanopores, obtained under the optimal technological conditions for process and constructive design of the vortex granulator, is represented.
