Abstract:
A process of forming an age-stabilized propellant composition, said process consisting essentially of the steps of:providing a quantity of ammonium nitrate;mixing an amount of synthetic zeolite having pores sized and adapted to absorb water with said ammonium nitrate to form a first mixture;aging said first mixture for a first aging period, wherein the first aging period is less than about 48 hours;grinding said first mixture to yield a second mixture so as to increase the absorbability and retention of water in the pores of the synthetic zeolite; andadding a binder with the second mixture to form a propellant composition, said binder being added in a sufficient amount to permit formation of said propellant composition into a desired shape, wherein said propellant composition is substantially smoke-free upon combustion.
