Microscopic observations of X-ray and gamma-ray induced decomposition of ammonium perchlorate crystals [PDF]
, 1972 The X-ray and gamma-ray induced decomposition of ammonium perchlorate was studied by optical, transmission, and scanning electron microscopy. This material is a commonly used oxidizer in solid propellents which could be employed in deep-space probes, and

Propellants, Explosives, Pyrotechnics, EarlyView.Ammonium dinitramide (ADN) and 3,4‐Diaminofurazan (DAF) form a 1:1 energetic cocrystal. We report its crystal structure and spectroscopic signature and evaluate thermal stability, decomposition behavior, hygroscopicity, and combustion properties. Propellant performance calculations benchmark the material against guanylurea dinitramide (GuDN) and ...

The anodic oxidation of bases in the solvent m-cresol [PDF]
, 1974 The oxidation of bases in the solvent m-cresol was investigated by polarography, voltammetry at the rotating platinum disc electrode and by chronopotentiometry. It was shown that the m-cresolate ion is the electroactive species in this reaction.

Bis(2-pyridylmethyl)ammonium perchlorate
Acta Crystallographica Section E Structure Reports Online, 2002 The title compound, C14H18N3+·ClO4−, a perchlorate salt of the monoprotonated form of bis(2-pyridylethyl)amine, has a structure in which one of the two H atoms on the amine N atom forms hydrogen bonds to the two pyridyl N atoms in a chelating fashion, while the second H atom on the amine is also used in hydrogen bonding to a perchlorate O atom.

Addition of solid oxidizer increases liquid fuel specific impulse [PDF]
, 1967 Adding soluble solid oxidizers to hydrazine and similar fuels makes them useful in low temperature bipropellant systems. These oxidizers improve the low specific impulse, high freezing point, low boiling point, and low density of the ...
