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.

Kinetics analysis of thermal decomposition of ammonium dinitramide (ADN)

Journal of Thermal Analysis and Calorimetry, 2016
Kinetics analyses were performed on the thermal decomposition of ammonium dinitramide (ADN) using thermogravimetry-differential thermal analysis–mass spectrometry–infrared spectroscopy (TG-DTA–MS–IR). The main evolved gases were determined to be NH3, H2O, N2, NO, N2O, and NO2.

Crystallization of Spherical Ammonium Dinitramide (ADN) Particles

Propellants, Explosives, Pyrotechnics, 2000
The described process aims to produce spherical ammonium dinitramide (ADN) particles of different sizes with a narrow particle size distribution. The crystallization process presented in this paper consists of two stages. In the first stage, molten ADN is dispersed in a continuous phase in which ADN is insoluble.

Nanocrystallisation of Ammonium DiNitramide (ADN) by Spray Flash Evaporation (SFE)

Propellants, Explosives, Pyrotechnics, 2018
AbstractAmmonium DiNitramide (ADN) is an interesting oxidizer to replace ammonium perchlorate in the composition of solid propellants. In this study, Spray Flash Evaporation (SFE) is presented as a new technology to enhance stability of ADN by crystallization of nanoparticles.

Modeling of ammonium dinitramide (ADN) monopropellant combustion with coupled condensed and gas phase kinetics

Combustion and Flame, 2014
Abstract A comprehensive multi-phase combustion model has been developed to study the physiochemical processes involved in the combustion of ammonium dinitramide (ADN). The numerical model is based on the conservation equations of mass, species concentration, and energy, and takes into account finite-rate chemical kinetics in both condensed and gas ...

The properties of ammonium dinitramide (ADN): Part 1, basic properties and spectroscopic data

Journal of Energetic Materials, 2000
Abstract Basic properties and spectroscopic data for the energetic oxidizer ADN (Ammonium dinitramide (NH4N(NO2)2)) are presented. The ADN used for this work was synthesized by a new efficient and environmentally friendly method. The method is based on a direct nitration of salts of sulfamic acid by ordinary mixed acid, followed by neutralization and ...

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.

CO2 Laser-Induced Combustion of Ammonium Dinitramide (ADN)

Combustion and Flame, 1998
Abstract Experimental studies of CO 2 laser-induced combustion of ammonium dinitramide (ADN) were performed to determine the key physical and chemical processes involved. Experimental conditions covered the range of 0.1–5.0 atmospheres in argon and incident laser heat fluxes of 20 to 300 W/cm 2 . Quantitative gaseous species measurements obtained by

Modeling the chemical reactions of ammonium dinitramide (ADN) in a flame

Combustion and Flame, 2001
Ammonium dinitramide (ADN) is a new energetic material that can be used as an oxidizer in solid rocket propellants. In the last few years, a number of papers devoted to the study of ADN combustion mechanism have been published. Molecular beam mass-spectrometry and thermocouple measurements are here used to study ADN flame structure at pressures of 0.3 ...
