Abstract

A granular ammonium nitrate or ammonium sulphate nitrate contains 0.1 to 5.0% by weight, based on the total weight of the composition, of aluminium hydroxide or a basic aluminium salt uniformly distributed within the granules. The material is prepared by feeding to a rotary granulator, a solid ammonium salt (ammonium sulphate or nitrate) a water-soluble aluminium salt (e.g. sulphate or nitrate), an aqueous solution of ammonium nitrate containing less than 20% by weight of water, recycle material (fines less than the product size of from 1.0-3.5 mm.s. and ground oversize) at an elevated temperature, and anhydrous ammonia, granulating the mixture at a temperature above 50 DEG C. and drying the granules, the amount of ammonia added being such that the pH of a 10% solution (by weight) of the granules in water is in the range 4.5-5.0.
