Abstract
This paper presents the result of a study of the chemical composition, physicotechnical properties and structure of various types of granulated ammonium nitrate (high-density, porous and) made in Russia and abroad. It is shown that heat treatment of high-density GOST 2-2013 ammonium nitrate granules leads to changes in the crystal structure (aeration) that increase the retention capacity relative to the fuel oil. The detonation velocity of ammonium nitrate/fuel oil compositions based on aerated ammonium nitrate was measured.
