“…In this paper, the ballistic e©ciency [1] of the ith launcher stage (E i ) de¦ned as E 1 = I sp ρ 0.6 ; E 2 = I sp ρ 0. 4 ; and E 3 = I sp ρ 0.2 is considered. The exponents values (0.2, 0.4, and 0.6) correspond to three-stage rocket launchers with optimized stage masses and tank volumes of every stage.…”

“…Therefore, a compound having acidic nature, e.g., oxalic acid, catalyzes AN decomposition. This catalysis depends upon various properties, in particular, upon component acidity, e.g., organic acids that are considerably weaker than oxalic do not a¨ect AN decomposition [4]. To date, the stability of AN-based formulations (if one means that ¤stability¥ is the ¤absence of other substances formation¥) is a solved problem.…”

The examination results of the gelatinization of nitrocellulose gunpowders, stabilized by different stabilizers are described in this study. The microstructure of gunpowder samples of different chemical compositions is analyzed by the scanning electron microscopy (SEM). Apart from the three-dimensional picture of morphology and the effect of the molecular dispersion of stabilizers into the nitrocellulose matrix, the information on chemical composition of the surface of gunpowder grain was obtained by the use of energy-dispersive X-rays spectrometry on SEM (SEM/EDX). The aim of the research was the comparative analysis of three different gunpowder samples, and the estimation of the effect on the gelatinization of nitrocellulose by different stabilizers was performed including their separate influences on the chemical stability of gunpowder. The comparative analysis is based on the degree of homogenous dispersion of each stabilizer in the matrix, which has the significant positive influence on the stability of gunpowder.

“…The thermal stability of this salt can be reduced by various impurities, among which the most dangerous are chlorides, acids and some organic compounds [18][19][20][21][22]. This property of ammonium nitrate was the cause of many devastating events, both accidental and deliberate [10,[23][24][25][26].…”

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.
