ABSTRACT:
Ammonium nitrate is phase-stabilized against Phase IV.rarw..fwdarw.Phase III transition and the undesired volume changes associated with that phase change by including an effective amount of at least one metal dinitramide salt having the formula MX.sub.n wherein M is a metal cation, X is a dinitramide anion, and n is 1, 2 or 3. The phase-stabilized ammonium nitrate is useful in energetic applications such as solid propellants and explosives.
