This article presents the results of a study on the production of non-caking ammonium nitrate (AN) samples by adding Glauber's salt (GS) powder to its melt. The AN : GS weight ratio was varied from 100 : 0.25 to 100 : 3. The resulting GS-nitrate melt was granulated using the prilling method. In accordance with the requirements of international GOST 2-2013, a sample obtained with an AN : GS weight ratio of 100 : 2.5 (AN-0.025GS) was selected as optimal for producing non-caking AN. It was found that the total nitrogen content of the AN-0.025GS sample was at least 34%, while the granule strength was 3.46 MPa, caking property was 2.58 kg/cm2, porosity was 7.96%, and diesel fuel absorption was 2.5 g, while in the traditional non-caking AN (AN-0.028MgO) with the addition of magnesite, taken for comparison, these indicators were 1.58 MPa, 4.67 kg/cm², 9.1% and 4.33 g respectively. GS can not only provide AN granules with low caking and explosiveness, but also improve their agrochemical properties. Thus, the prepared optimal sample of AN-0.025GS, in addition to 34.06% nitrogen for plant nutrition and 100% absorption, also contains beneficial elements such as 1.01% Na2O and 1.22% SO3. Thus, the use of GS as a modifying additive can be considered an effective and promising approach to improving the stability, safety, and controllability of granular nitrogen fertilizers based on AN.
