Abstract

Ammonium nitrate having improved free-flowing properties and resistance to caking is obtained by adding to crystalline ammonium nitrate from 0,2% to 1% by weight of a finely divided inert material and from 0,02% to 0,2% by weight of an aliphatic amine. The inert material may be precipitated calcium carbonate or calcium sulphate hemihydrate; the amine may contain aliphatic radicals of up to 25 carbon atoms, and may be octadecylamine. The amine may be added before or after the addition of the inert material, or may be mixed with the inert material first, preferably when hot, and then added to the ammonium nitrate. Examples are given.
