Abstract
Ammonium nitrate (AN) is a universal and agro chemically valuable nitrogen fertilizer. It is effective on all types of soils and for almost all crops. However, this fertilizer has two serious drawbacks – its caking during storage and increased explosion hazard. The theory of the caking process of granular AN is discussed in some detail in the literature and possible ways to eliminate it are shown. To eliminate the disadvantages inherent in AN, methods have been developed by introducing various additives into its composition. These additives can be divided into the following main groups: additives that bind free moisture; additives affecting the process of polymorphic transformations; dusting granules and treating them with surfactants and additives that form crystallization centers.
