ABSTRACT:
Ammonium nitrate is phase-stabilized by a synergistic phase stabilization additive combination of at least cupric oxide and potassium nitrate. Specifically, phase-stabilized ammonium nitrate contains between about 94.0 and about 96.0 wt. % ammonium nitrate and between about 4 and 6 wt. % of a synergistic phase stabilization additive combination of at least cupric oxide and potassium nitrate, wherein the cupric oxide is present in a relative amount of no more than about 2.0 wt. %. In some cases, additional stability is imparted by the inclusion of zinc oxide such as in a relative amount of no more than about 1.5 wt. %.
