How to thermal decomposition of ammonium perchlorate and the energy realeased from it’s decomposition is effective on the burning rate of propellant.Therefore, various catalysts can be used to improve the combustion properties of ammounium perchlorate .Crystalline transition metal oxides (TMOs) with diverse morphological structure have attracted tremendous attention during the last decade. Amon...

Use of energetic plasticizer, N-Butyl-N-(2-Nitroxyethyl) Nitramine (BuNENA), in the propellants’ formulations, has some advantages such as not migration in the fuel, high thermal stability, low sensitivity of the propellant formulation, improvement in mechanical properties and raising the impulse due to light molecular weight of combustion gases. In this study two acidic ionic liquids ([(...
This synthesis discusses the emissions of carbon dioxide from fossil-fuel combustion and cement production. While much is known about these emissions, there is still much that is unknown about the details surrounding these emissions. This synthesis explores our knowledge of these emissions in terms of why there is concern about them; how they are calculated; the major global efforts on inventor...
specific surface area increment of alumina nanoparticles using mineral fuels in combustion synthesis
ammonium carbonate and ammonium sulfate have been proposed and used as two new fuels for synthesizing gamma alumina nanoparticles. the prepared samples have been characterized by x-ray diffraction (xrd), 2 n adsorption (bet) and transmission electron microscopy (tem). a comparison has been made between the properties of the nanoparticles synthesized by these two fuels and other conventional fu...
