The Synthesis of the Aluminum Hydride and its Application in Composite Propellants
Journal Title: Problemy Mechatroniki. Uzbrojenie, lotnictwo, inżynieria bezpieczeństwa - Year 2013, Vol 4, Issue 1
Abstract
Results of the research focusing on the wet synthesis of aluminum hydride (AlH3) were summarized. The compound is the object of interest in hydrogen storage due to its high concentration of hydrogen (10,1% by mass). Composite propellants containing 20-25% of AlH3 can achieve high specific impulse, up to 300 seconds. In the paper the synthesis of the compound is described and the key stabilization method is underlined. The scanning electron microscopy picture of the crystals were shown. The stabilized form of the AlH3 were used to prepare samples of composite propellants and their basic parameters were measured. AlH3 as an ingredient of composite propellants significantly increases the heat of combustion and the rate of burning.
