AB  - 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.
AB  - U radu su prikazani rezultati ispitivanja želatinizacije nitroceluloznih baruta, stabilisanih različitim tipovima stabilizatora. Pomoću skenirajuće elektronske mikroskopije (Scanning Electron Microscopy, SEM) ispitivana je mikrostruktura uzoraka baruta različitog hemijskog sastava. Pored trodimenzionalne slike topografije i učinka molekularne disperzije stabilizatora u matricu nitroceluloze, pomoću metode energetske diperzije X-zraka (Energy-Dispersive X-Rays Spectroscopy - EDX) dobijena je informacija o kvantitativnom i kvalitativnom hemijskom sastavu ispitivanog dela površine barutnog zrna. Na osnovu komparativne analize, izvršena je ocena efekta želatinizacije nitroceluloze različitim tipovima stabilizatora i njihov pojedinačni uticaj na hemijsku stabilnost baruta.

AB  - The study describes the results of static, physicochemical and ballistic examination of double-based gunpowder charges, in order to establish the deviations from the demanded quality of mortar ammunition. The examinations were carried out on gunpowder samples used for laboration of mortar shells 60, 82 and 120 mm caliber and consisted of periodical measurements of the gunpowder mass loss, basic ballistic parameters, and compatibility testing of gunpowder and celluloid containers as well as chemical stability determination. The estimation of the gunpowder quality was performed by comparative analysis and the suggestions for more efficient production of it were given.

AB  - This paper reports the characteristics of the explosive TH-5, recycled (recovered) trinitrotoluene (TNT) with max. 5wt-% of hexogen (RDX). The explosive TH-5 was obtained by delaboration of warheads and melting of explosive charges based on TNT and RDX and by separation (extraction) of high explosive components. The thermal characteristics of pure (virgin) TNT and RDX, and recycled explosive TH-5 are determined by differential scanning calorimetry. The possibility of processing TH-5 by pressing and casting is also examined. The comparative analysis of sensitivity of TH-5 and TNT to friction is determined, as well as compressibility of explosives, and the detonation velocity of pressed and cast charges. Based on the analysis of experimental results, the defense standard requirements for the quality of TH-5 are defined and possibility of practical application of explosive TH-5 was estimated.
