Ammonium dinitramide (ADN) is a promising oxidizing agent for solid rocket propellants. In situ XRD investigations of ADN and suspensions have been performed in order to understand refine the emulsion crystallization process manufacturing spherical particles (prills). The investigation revealed that melt behavior depends on quality, humidity, maximum temperature cycles, suspension agents. Furth...
The goal of the EU Horizon2020 project Rheform is the replacement of hydrazine with liquid propellants based on ammonium dinitramide (ADN) for orbital and launcher propulsion systems. Hydrazine and its derivatives are the standard propellants for spacecraft propulsion system since the 1960s, but they are highly toxic and carcinogenic. New regulations will lead to restriction of their use in the...
Midinfrared Absorption Measurements of Nitrous Oxide in Ammonium Dinitramide Monopropellant Thruster
A T-jump/time-of-flight mass spectrometer (T-Jump/TOFMS) is used to probe the decomposition of several aminotetrazole containing energetic materials under very high heating rates of 10(5)-10(6) K/s. The materials investigated are 5-amino-1-methyl-1H-tetrazolium dinitramide (MeHAT_DN), 1,5-diamino-4-methyl-1H-tetrazolium dinitramide (MeDAT_DN), 1,5-diamino-1H-tetrazolium nitrate (DAT_N), 1,5-dia...
The crystal structure of solvate-free silver dinitramide (Ag[N(NO(2))(2)]) was determined by X-ray diffraction for the first time and displays secondary contacts between silver and oxygen as well as between silver and nitrogen, furnishing different coordination modes of the dinitramide moiety.
Ammonium dinitramide (ADN) is a class 1.1 explosive oxidizer that can be used in solid rocket propellant mixtures and explosives. A 90-day general toxicity/ reproductive screen performed on this compound at doses of 162, 103, 29, and 0.0 mg ADN/kg/day resulted in a treatment-related adverse effect on litter production. Incidences of animals producing litters (1/11, 3/12, 12/12, and 11/12, respe...
