It forms colorless monoclinic crystals. It is hygroscopic, and is a strong oxidizing and nitrating agent. It may become hypergolic in contact with organic materials. Nitronium perchlorate was investigated as an oxidizer in solid rocket propellants. Thomas N. Scortia filed for patent on such propellant in 1963.〔Thomas N. Scortia. (NITRONIUM PERCHLORATE PROPELLANT COMPOSITION ), USPTO patent number 3575744, filed Mar 27, 1963; issued Apr 20, 1971; assignee: United Aircraft 5 Corporation.〕 However its reactivity and incompatibility with many materials hindered such use. Coating of nitronium perchlorate particles with ammonium nitrate, prepared in situ by passing of dry ammonia gas over the particles, was investigated and a patent was awarded.〔Diebold, James P. (17 April 1973). (Encapsulation of Nitronium Perchlorate Employing Ammonia to Form Ammonium Perchlorate. ) (Patent) Department of the Navy, Washington DC. Accession Number: AD0164909.〕 Decomposition rate of nitronium perchlorate can be altered by doping with multivalent cations.〔(NITRANIUM PERCHLORATE REACTION RATE ALTERATION ). USPTO patent number 3770527.〕 Nitronium perchlorate and ammonium perchlorate do not produce smoke when stoicheometrically burned with non-metallic fuels. Potassium perchlorate and other metal perchlorates generate smoke as the metal chlorides are solid materials creating aerosols of their particles. Of all perchlorates, nitronium perchlorate is the most powerful oxidizer. It can be easily detonated, however.〔(Thiokol Propulsion: Rockets Basics - A Guide to Solid Propellant Rocketry ).
