Chemical compound

Nitronium perchlorate, NO₂ClO₄, also known asnitryl perchlorate andnitroxyl perchlorate, is aninorganic chemical, thesalt of theperchlorate anion and thenitronium cation. It forms colorlessmonoclinic crystals. It ishygroscopic, and is a strongoxidizing andnitrating agent. It may becomehypergolic in contact with organic materials.

Nitronium perchlorate was investigated as anoxidizer insolid rocket propellants.Thomas N. Scortia filed for patent on such propellant in 1963,^[3] however, its reactivity and incompatibility with many materials hindered such use. Coating of nitronium perchlorate particles withammonium nitrate, prepared in situ by passing of dryammonia gas over the particles, was investigated, and a patent was awarded.^[4]

The decomposition rate of nitronium perchlorate can be altered by doping withmultivalent cations.^[5]

Nitronium perchlorate and ammonium perchlorate do not produce smoke when stoichiometrically burned with non-metallic fuels. Potassium perchlorate and other metal perchlorates generate smoke, as the metal chlorides are solid materials creatingaerosols of their particles. Of all the perchlorates, nitronium perchlorate is the most powerful oxidizer. It can be easilydetonated.^[6]
