چکیده

Complex ammonium nitrate-based NP and NPK fertilizers are multicomponent salt systems prone to high hygroscopicity, caking and explosive thermal decomposition. The slurries that used in the production of these fertilizers can also exhibit insufficient thermal stability. One of the most important issues for such slurries is their viscosity, which determines the energy costs for transportation and processing into the final product. Increasing the degree of phosphoric acid ammoniation helps to reduce the ammonium nitrate’s content in the product, but the main question remains about the properties of such fertilizers. This article is devoted to studying properties of complex NP and NPK ammonium nitrate-based fertilizers and their intermediates with increasing the degree of phosphoric acid ammoniation.
