Abstract
A material for a pyrotechnic composition and related pyrotechnic compositions are provided in which the material includes a substituted basic metal nitrate including a reaction product of an acidic organic compound and a basic metal nitrate. A method for enhancing a burn rate of a gas generant composition and a burn rate enhanced gas generant composition including a reaction product of basic metal nitrate and tetrazoles, tetrazole derivatives, and combinations thereof, and a nitrogen-containing co-fuel such as guanidine nitrate are also disclosed. The burn rate enhance gas generant composition may optionally include an additional oxidizer such as basic copper nitrate.
Claims34
A material for use in a pyrotechnic composition comprising:
- a substituted basic metal nitrate;
- wherein the substituted basic metal nitrate includes a reaction product of an acidic organic compound and a basic metal nitrate.
A burn rate enhanced gas generant composition comprising:
- about 5 to about 95 composition weight percent substituted basic copper nitrate, the substituted basic copper nitrate including a reaction product of an acidic organic compound and a basic copper nitrate;
- and
- about 5 to about 60 composition weight percent guanidine nitrate co-fuel,
- wherein the acidic organic compound is selected from the group consisting of tetrazoles, tetrazole derivatives, and combinations thereof.
