Ammonium Dinitramide:  Kinetics and Mechanism of Thermal Decomposition

The Journal of Physical Chemistry A, 1997
Thermal decomposition of ammonium dinitramide (ADN) has been studied by differential scanning calorimetry (DSC) and thermal gravimetry combined with mass spectrometry (TG−MS). ADN decomposes in the range 130−230 °C with an overall heat release of 240 ± 40 kJ mol-1.

Thermal analysis of ammonium dinitramide (ADN)

Thermochimica Acta, 2000
Abstract Kinetic constants of decomposition were determined for ADN and prilled ADN by DSC and TG. Pressure DSC at 550 psi air or helium had similar kinetic constants for prilled ADN, namely 29 kcal/mol activation energy and a log frequency factor of ∼14.0 min−1.

Characteristics of NEPE Propellant with Ammonium Dinitramide (ADN)

Advanced Materials Research, 2011
The theoretical performances of NEPE (nitrate ester plasticized polyether) propellant with and without ADN were calculated with minimum free energy method. The burning characteristics and the thermal decomposition of propellants were determined by nickel chromium wire method and TG- DTG, respectively.

Study on the Crystal Structure and Hygroscopicity of Ammonium Dinitramide

Journal of Chemical & Engineering Data, 2010
Ammonium dinitramide (ADN), NH4N(NO2)2, is one of the most promising oxidizing components of future solid propellant formulations, because it is eco-friendly and more energetic and has no plume signature because there is no chlorine in its molecular structure. The hygroscopicity of the ADN crystal, which is more severe than that of ammonium perchlorate

Thermal behavior of new oxidizer ammonium dinitramide

Journal of Thermal Analysis and Calorimetry, 2012
Ammonium dinitramide (ADN) is a promising new oxidizer for solid propellants because of its high oxygen balance and high energy content, and halogen-free combustion products. One of the characteristics needed for solid propellants is stability. Heat, light, and moisture are factors affecting stability during storage, manufacture, and use. For practical

Heat-release mechanism in ammonium dinitramide flame

Combustion, Explosion, and Shock Waves, 2007
To verify the adequacy of various models of heat release in ammonium dinitramide flame to real processes, chemical processes in products of thermal decomposition at a pressure of 10 torr and in ammonium dinitramide [ADN; NH4N(NO2)2] flame at a pressure of 0.4 to 60 atm are numerically simulated. The calculations are performed on the basis of a detailed
