ABSTRACT:
In a gas generant composition containing a source of ammonia, such as an ammonium salt or an ammonia-transitional metal complex that emits ammonia as a degradation product, a zeolite, particularly chabazite, is added as an ammonia-absorbing material. In gas generant formulations containing a copper compound and a nitrate source, the zeolite acts to reduce or prevent formation of copper tetrammine dinitrate.
