Thermal Decomposition of Ammonium Dinitramide (ADN) as Green Energy Source for Space Propulsion
Aerospace, 2023 The thermal decomposition of an ammonium dinitramide-based energetic compound was conducted for the first time using a dispersive inductively coupled plasma mass spectrometer, DTA-TG analysis, and pyrolysis at a constant temperature. A liquid droplet was

Decomposition Pathways of Ammonium Dinitramide (ADN) and its HNO3‐Clusters Elucidated by DFT‐Calculations [PDF]
Propellants, 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]
, 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). These propellants are well known for their good performance characteristics, but their limitations and liabilities regarding toxicity, operational handling and ...

A Smart Access to the Dinitramide Anion - The Use of Dinitraminic Acid for the Preparation of Nitrogen-Rich Energetic Copper(II) Complexes. [PDF]
Chemistry, 2021 The dinitramide anion was made accessible for complexation through the use of dinitraminic acid and basic copper(II) carbonate. The in situ prepared copper dinitramide was complexed by 13 different highly endothermic tri‐ and tetrazole ligands. By the choice of ligand, complexes were obtained that possess thermal stability exceeding 200 degrees Celsius,
