Abstract

A method for forming an ionically bonded ammonium dinitramide salt having the formula NH4 30 N(NO2)2 - useful as a stable oxidizer for solid fuel rocket propellant or explosive formulations is disclosed. The ammonium dinitramide salt is formed by the reaction of ammonia and a nitronium-containing compound, such as a nitronium salt or a covalently bonded compound containing a NO2 - group, at a temperature of from about - 20° C. to about 120° C. The nitronium-containing compound may be either a covalently bonded compound containing a NO2 - group or a nitronium salt having the formula (NO2 +)n X-n, where X is the anion of the nitronium salt and n= 1-2.
