Hygroscopicity of Ammonium Nitrate Samples

Abstract

Ammonium nitrate is a component of many explosive systems, but a disadvantage in its use is its hygroscopicity. To extend the shelf life of explosives containing ammonium nitrate, it is important to minimize its hygroscopicity. Samples of ammonium nitrate were tested for hygroscopicity at relative humidity levels of 60%, 70%, 80% and 90% and between 28-30C. Most of the samples of ammonium nitrate were coated; some were manufactured by a process producing prills; clay material was added in two cases. The results indicated that the ammonium nitrate which contained the least amount of impurities or additives also was the least hygroscopic.
