Abstract
Low-smoke gas generating compositions for producing a low order pressure pulse use a salt or complex of a triazolyl-tetrazinyl-triazine compound. The general chemical structure of the triazolyl-tetrazinyl-triazine is:wherein Z+, when present, is H+ or a cation; R1 is an electron donating group and wherein m=1, 2 or 3; t=0 or 1, and n=0, 1, 2 or 3; and when present, R is a complexing component and x=1, 2 or 3; wherein either Z or R may be absent.
