Thermal Stability of Ammonium Nitrate in Two-Component Mixtures with Powdered and Fine-Grained Materials

Abstract. Ammonium nitrate(V) (AN, NH4NO3) is widely and used in the chemical industry, agriculture as a fertilizer, explosive for military civil purposes (e.g. mining) or solid propellant [1, 2]. Storage of ammonium nitrate poses many problems, it may be hazardous. This was proven, example, by explosion 2020 Beirut. stored warehouse at port among other wares an unfortunate turn events caused huge explosion. The contributed to formation 140-meter crater earthquake with magnitude 3.3 on Richter scale. classified third most destructive urban all time, after atomic bombs Hiroshima Nagasaki end World War II [3, 4], mixtures oils (fuel gas) concentrated form nitrogen fertilizer  explosives [5]. dangerous properties AN have been extensively studied. It known that pure stable room temperature but explode when mixed impurities confined space under fire-hazard conditions [1]. research aimed analyze changes occurring two-component powdered fine-grained materials assess effect such admixture fertilizer. Thermal analysis carry out TG-DSC tests.
