Abstract
The use of an aluminum silicate molecular sieve as a stabilizer in propelts that give off gas during the aging process. An aluminum silicate molecular sieve is added to propellants that give off gases such as N.sub.2, CO.sub.2, CO, F.sub.2 and NO.sub.x during the aging process. The aluminum silicate molecular sieve is selected to have a pore size of less than about 10 angstroms. This brings about absorption of these undesirable gases during the aging process and thereby prevents degradation of the propellant.
Claims1
In a solid propellant selected from the group consisting of casting power of nitrocellulose and nitroglycerin, high energy fluorine propellant, single base nitrate ester propellant, double base nitrate ester propellant and ammonium perchlorate/Al with rubber binder propellant, that gives off gases selected from the group consisting of N.sub.2, CO.sub.2, CO, F.sub.2 and NO.sub.x during the aging process, the improvement consisting of an additional ingredient in said propellant of an aluminum silicate molecular sieve having a particulate size of less than about 10 microns, a pore size of less than about 10 angstroms, and in an amount of about 0.2 percent by weight of said propellant.
