“…This last phenomenon can be connected with gradual change in color of samples from brown to almost black, characteristic for samples after heating at 800°C. Analysis of results obtained during investigation of tungsten precursor WP and brown solid FeVW indicates that exothermic effects recorded on DTA curves of WP and FeVW can be attributed to oxidation of ammonia [10,14,[25][26][27]. It is worth to say that strong exothermic effect recorded on DTA curve of WP with maximum at 440°C is shifted in the case of FeVW toward lower temperatures with maximum at 240°C.…”

“…It is worth to say that strong exothermic effect recorded on DTA curve of WP with maximum at 440°C is shifted in the case of FeVW toward lower temperatures with maximum at 240°C. According to literature data, NH 4 NO 3 , which was detected in FeVW sample, melts at 169.6°C and then starts to dissociate into NH 3 and HNO 3 [25][26][27]. Next, NH 3 is oxidized by decomposition products of HNO 3 .…”

“…Regardless of the mechanism, the first step of decomposition is always an endothermic dissociation of ammonium nitrate to ammonia and nitric acid. All further reactions are exothermic [10][11][12][13]. However, depending on the surface-to-volume ratio of the sample, endothermic surface evaporation may dominate the decomposition process [14,15].…”

Fertilisers containing ammonium nitrate are the most efficient sources of nitrogen used in agriculture. The major hazard associated with production, storage and transport of materials containing this compound is its liability to rapid decomposition, or even detonation under certain conditions. Properly selected calcium and magnesium carbonates may increase the thermal stability of ammonium nitrate. The aim of this research was to determine the influence of the carbonate mineral type and composition on phase transitions and decomposition process of fertiliser-grade ammonium nitrate. The article focuses on the methodology of thermal analysis of samples containing ammonium nitrate with carbonates and points out the phenomena and thermal characteristics that should be taken into consideration when testing fertiliser mixtures. Two different sample preparation methods allowed for investigating processes that may occur in inappropriate storage and transport conditions as well as during the production of fertiliser. The measurements were taken using techniques of differential thermal analysis and thermogravimetry coupled with mass spectrometry. The results showed that too high a level of carbonates reactivity can cause problems during the production of fertiliser, reducing the effectiveness of the filler in a final product.

Ammonium Nitrate Temperature‐Programmed Decomposition on Fe–Zeolite Catalysts: Effect of Deposition Method

The N2O formation during NOx selective catalytic reduction by NH3 is often attributed to NH4NO3 intermediate decomposition. Thermal decomposition of NH4NO3 has been extensively studied owing to the combination of its wide use as fertilizer and its dangerous properties. However, the decomposition of NH4NO3 in the presence of a catalyst has generated less attention. The decomposition of NH4NO3 may yield NxOy‐type products such as NO, NO2, N2O, N2 as well as HNO3 and H2O. This work focuses on the emissions of N2O. The deposition of NH4NO3 onto a Fe–zeolite catalyst was carried out by dry impregnation, by using a dilute solution of NH4NO3, and by a mechanical mixture. In the absence of catalyst, the release of N2O strongly depends on the conditions of the experiment (static or dynamic). The presence of a catalyst and the method of mixing ammonium nitrate into it affects its decomposition. Nitrogen formation is much more significant for the impregnated sample. For the mechanically mixed sample, the ammonium nitrate is mainly decomposed into N2O and NO2. N2O from ammonia oxidation was also detected in the presence of a catalyst.
