Influence of Preconditioning on the Absorbency and Strengh of Ammonium Nitrate Granules Grade B

The retention capacity of granulated ammonium nitrate grade B with respect to the liquid fuel due to pretreatment of the granules has been increased, and energy-condensed systems for mining have been developed. Processing technology including opening of hard shell of granules without formation of through pores and creating a rigid framework of slightly soluble compounds in the pores. It has been found, that treatment with a solution of iron (III) chloride and further heating provides formation of iron (III) hydroxyl compounds framework with the developed surface in the pores of granules.
