The present invention is directed to an age-stabilized and/or strengthened ammonium nitrate propellant composition wherein the strengthening agent is selected from the group consisting of azodicarbonamide, dicyandiamide, oxamide and mixtures thereof and wherein the age-stabilizing agent is a molecular sieve having a pore size of 13 angstroms or less.
1. An age-stabilized ammonium nitrate propellant composition consisting essentially of:ammonium nitrate having a crystalline phase present in an amount from about 40% to about 85%, a synthetic zeolite having a pore size from about 3 angstroms to about 13 angstroms present in an amount from about 0.2% to about 0.4%, and a binder present in an amount from about 3% to about 40% by weight of said composition, wherein said ammonium nitrate, synthetic zeolite and binder are each present in an amount effective to stabilize the crystalline phase of said ammonium...
