Abstract:
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 nitrate, provide said composition a shelf-life of at least about 5 years, and produce a composition that is substantially smoke-free upon combustion.
