METHOD FOR PRODUCTION OF AMMONIUM NITRATE

摘要

FIELD: production of crystalline materials having improved physical and chemical characteristics. SUBSTANCE: proposed method involves insertion of small amounts of inorganic material into melt of ammonium nitrate. Substantial amount of said additives is directly inserted into crystalline lattice of NHNO. Mentioned above impurities are inserted during fast crystallization of melt comprising 0.1-1.0 % of additive. Hygroscopic point of thus treated ammonium nitrate is increased by 2.5-3.5 % of its relative moisture content. EFFECT: improved hygroscopicity of desired ammonium nitrate.
