Thermal stability of ammonium dinitramide
Thermochimica Acta, 2002Abstract The low temperature thermal stability of ammonium dinitramide (ADN) and efforts to improve the thermal stability are presented. The decomposition rates of ADN at 60, 70, 80, and 90 °C were investigated. Several potential thermal stabilizers were investigated to suppress the low temperature decomposition (60–90 °C) of ADN.

Propellants, Explosives, Pyrotechnics, 2004
AbstractIn recent years, there has been a considerable interest in the development of novel type of high performance propellants for use in solid rocket motors. Ammonium salt of dinitramidic acid NH4N(NO2)2 (ADN) has attracted wide interest as a potentially useful energetic oxidizer for rocket propellants because of its clean and environment‐friendly ...

Energetics of ammonium dinitramide decomposition steps
Computational and Theoretical Chemistry, 1998Abstract The structures, energies at 0 K and enthalpies at 298 K have been computed for 37 molecules, ions and transition states that have been implicated in the thermal decomposition of ammonium dinitramide. A density functional procedure was used: DF/B3P86/6–31 + G ∗∗.

Ammonium Dinitramide (ADN)–Prilling, Coating, and Characterization
Propellants, Explosives, Pyrotechnics, 2009AbstractAmmonium dinitramide (ADN) is the promising oxidizer, which is expected to be applied, e.g., in solid rocket propellants. The manufacturing of spherical ADN particles (the so‐called ADN‐Prills) with useful morphology and reproducible quality is realized by means of the emulsion crystallization process.

Combustion of Propellants with Ammonium Dinitramide
Propellants, Explosives, Pyrotechnics, 1998AbstractThis paper reports a series of experiments involving ammonium dinitramide (ADN), a new energetic oxidizer of potential use in composite solid propellants. The experiments include (a) self‐deflagration of pressed pellets of ADN; (b) combustion of sandwiches with ADN laminae on both sides of a binder lamina that is either “pure” or filled with ...

Research on optimizing the synthesis of ammonium dinitramide
Journal of Military Science and Technology, 2022Ammonium dinitramide (ADN) is one of the potential oxidants in solid propellant formulations because it is environmentally friendly, has a high specific impulse, and has minimum signature exhaust gases. ADN was synthesized through the nitration reaction of potassium sulfamate salt with a mixture of sulfuric acid and nitric acid.

Combustion of ammonium dinitramide
Combustion and Flame, 1999The burning rate of ammonium dinitramide (ADN) has been studied as a function of pressure and different additives, the temperatures in the combustion front, and the composition of combustion products. Some kinetic characteristics of decomposition have been also obtained.

Hazardous Properties of Molten Ammonium Dinitramide
Propellants, Explosives, Pyrotechnics, 2020AbstractThe purpose of this article is to alert our peers on the danger faced by those who carry out experiments involving molten ammonium dinitramide (ADN). In recent experiments aiming at preparing submicron particles of this compound, a preliminary study of the sensitivity to impact of molten ADN was performed.

On the Anomalous Decomposition and Reactivity of Ammonium and Potassium Dinitramide
The Journal of Physical Chemistry A, 2010Mechanistic pathways for the thermal decomposition of the solid-state energetic oxidizers ammonium dinitramide (ADN) and potassium dinitramide (KDN) have been deciphered by carefully considering previously performed experimental studies and using state of the art quantum chemical modeling of molecular clusters.
