Abstract
Gas generant compositions are provided which compositions react to produce nitrogen gas and which compositions include guanylurea nitrate and at least one transition metal-containing water-compatible oxidizer. Also, related methods of gas generation are provided.
Claims26
A gas generating composition comprising:
- guanylurea nitrate and
- at least one transition metal-containing water-compatible oxidizer present in sufficient relative amount such that, upon combustion reaction initiation of the at least one transition metal-containing water-compatible oxidizer with the guanylurea nitrate, reaction products including a quantity of nitrogen gas are produced, and
- wherein said gas generating composition has a flame temperature of less than 2200 K.
A gas generating composition comprising:
- a fuel component in a relative amount of between about 20 to about 70 composition weight percent, wherein between about 10 to 100 percent of the fuel component is guanylurea nitrate and
- an oxidizer component in a relative amount of between about 30 to about 80 composition weight percent, wherein the oxidizer component includes at least one transition metal-containing basic metal nitrate oxidizer present in sufficient relative amount such that, upon combustion reaction initiation of the at least one transition metal-containing basic metal nitrate oxidizer with the guanylurea nitrate, reaction products including a quantity of nitrogen gas are produced, and
- wherein said gas generating composition has a flame temperature of less than 2200 K.
A gas generating composition comprising:
- a fuel component in a relative amount of between about 20 to about 70 composition weight percent, wherein between about 10 to 100 percent of the fuel component is guanylurea nitrate and
- an oxidizer component in a relative amount of between about 30 to about 80 composition weight percent, wherein the oxidizer component includes at least one transition metal-containing metal ammine nitrate oxidizer present in sufficient relative amount such that, upon combustion reaction initiation of the at least one transition metal-containing metal ammine nitrate oxidizer with the guanylurea nitrate, reaction products including a quantity of nitrogen gas are produced, and
- wherein said gas generating composition has a flame temperature of less than 2200 K.
