The radiometric performance and burn rate of four spectral fare compositions (R-X) based on 1,4-dicyanobenzene (1), 3,5-dinitrobenzonitrile (2), E-stilbene (3) and 9,10-dihydroanthracene (4), potassium perchlorate and polyacrylate binder are described. The burn rates, spectral effciencies, Eλ, in both α- and β-band have been determined. The composition R-4 displays the highest effciency in both α-...
The detonation of energetic materials will result in the formation of decomposition products. These may be carbon monoxide, carbon dioxide, carbon, water, etc. In order to clarify the problems of decomposition products, a software package is developed to solve the problems of decomposition products using four different concepts. Although each concept will provide a different answer for the decomposition...
Search of high-power energetic materials is one primary line of development of chemical physics of combustion and explosion. Yield of such materials is usually very small, and its cost is very high. Calculation of unknown characteristics and properties is the only way out from this situation. There are different methods today that allow calculating unknown detonation performance and some of physicochemical...
Synthesis of new high-strength superdispersed materials by use of detonation and shock waves is a developing branch of manufacture. Diamond, metal oxides, nitrides, and many other substances are produced and find industrial application. The objective of current work was the method of synthesis of iron aluminates and a new modification of alumina. For the synthesis initiation of explosion of aluminized...
Hydrazinium 5-aminotetrazolate (2) was synthesized via two facile routes. Both the reaction of 5-amino-1H-tetrazole (1) with hydrazine hydrate in aqueous solution and the reaction of 1 with diluted hydrazine solution in THF yield 2 in excellent purities and yields. 2 was characterized comprehensively by X-ray diffraction, IR, Raman and multinuclear NMR spectroscopy, mass spectrometry, elemental analysis...
This paper presents the results of thermodynamical calculations and investigations of the thermochemical and balistic properties of aluminized composite solid propellants Binder/AP/A1 containing FOX-7. The calculation was conducted by using ICT-Thermodynamic Code. The heat of combustion was determined in a stationary bomb calorimeter IKA C 4000. The breakdown temperatures were taken with the DTA 551...
Modern rocket propellants contain inter alia nitroamines (i.e. RDX, HMX). Therefore, the detonation properties of composite solid propellants are very important for good functioning of rocket motors and for storage. One of the new materials of that kind, with low sensitivity, is FOX-7 which was applied here as one of the components of composite solid propellant. This paper presents the thermodynamical...
Textural properties of iron powders obtained by reduction of iron(II) compounds and by electrolysis were determined. Their specific surfaces were 0.38 and 0.43 m2g-1 respectively, and the prevailing grain sizes amounted to 10 and 43 ?m respectively. Total content of the determined metallic impurities was 0.055 wt.% in the preparation obtained by the electrolysis while in the preparation obtained by...
Some of pe roxide s : t r i a c e tone t r ipe roxide (TATP) , hexamethylenetriperoxidediamine (HMTD) have been used recently as "irregular" explosives for delinquency and international terrorism purposes. The intimate knowledge of properties and methods of analysis of these substances is necessary for experts. Forensic investigations of some peroxides explosives: triacetonetriperoxide (TATP)...
