Problems solved by technology

The prior art generally fails to provide gas generant compositions, particularly non-azide gas generant compositions that are capable of simultaneously providing or resulting in relatively high gas yields, as well as sufficient and desirably high burn rates while avoiding or minimizing production or yield of undesirable inflatio

example 1

[0065] The same procedure as in Comparative Example 1 except that, 1) 5-aminotetrazole and bCN were reacted in water at 190° F. for 1 hour in order to make the 5-AT / bCN complex and 2) cupric oxide and diammonium bitetrazole were reacted in water at 190° F. for 1 hour in order to make the copper diammonium bitetrazole prior to the addition of the other ingredients.

Abstract

A gas generant composition includes a non-azide, organic, nitrogen-containing fuel; a substituted basic metal nitrate and at least one transition metal complex of diammonium bitetrazole. The substituted basic metal nitrate can be a reaction product of an acidic organic compound and a basic metal nitrate. The transition metal complex of diammonium bitetrazole is effective to enhance the burn rate presure sensitivity of the gas generant composition as compared to the same gas generant composition without inclusion of the at least one transition metal complex of diammonium bitetrazole.
