Amine-AlH₃ Adducts as Energetic Materials for a New Generation of Solid Fuels. [PDF]

Chemistry
New amine‐AlH₃ adducts offer a more environmentally friendly, high‐energy alternative to conventional rocket propellants, and exhibit ultra‐fast ignition. They can be synthesized by mechanochemical method under hydrogen pressure starting from aluminum metal directly or by wet chemical processes with AlH3.
