Decomposition Pathways of Ammonium Dinitramide (ADN) and its HNO 3 ‐Clusters Elucidated by DFT‐Calculations [PDF]

open access: yesPropellants, Explosives, Pyrotechnics, 2020
AbstractAmmonium dinitramide (ADN) may serve as a ‘green’ oxidizer for rocket propellants since it provides chlorine free and minimum signature exhaust gases. However, stability issues and an erratic decomposition behaviour limit its non‐questionable general usability.

Green Propellants Based on Ammonium Dinitramide (ADN) [PDF]

open access: yes, 2011
Ammonium perchlorate (AP) and hydrazine are today widely used as propellants. AP as oxidizer in solid propellants and hydrazine as liquid monopropellant (Brown, 1995; Sutton and Biblarz, 2001).
