Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
94 words
A solid gas generating composition comprising a compressed mixture of (a) about 53 to 92 weight percent of a perfluoroammonium salt of a fluorinated Lewis acid selected from the group consisting of perfluoroammonium tetrafluoroborate, perfluoroammonium hexa fluoroarsenate, and perfluoroammonium hexafluoroantimonate; (b) about 0.5 to 2 weight percent of a metal nitride selected from the group consisting of aluminum nitride, magnesium nitride, and lithium nitride; and (c) about 7 to 46 weight percent of an alkali metal fluoride selected from the group consisting of lithium fluoride, sodium fluoride, potassium fluoride, rubidium fluoride, and cesium fluoride.
Claim 2
Dependent Claim
94 words
A solid gas generating composition comprising a compressed mixture of (a) about 53 to 92 weight percent of a perfluoroammonium salt of a fluorinated Lewis acid selected from the group consisting of perfluoroammonium tetrafluoroborate, perfluoroammonium hexa fluoroarsenate, and perfluoroammonium hexafluoroantimonate; (b) about 0.5 to 2 weight percent of a metal nitride selected from the group consisting of aluminum nitride, magnesium nitride, and lithium nitride; and (c) about 7 to 46 weight percent of an alkali metal fluoride selected from the group consisting of lithium fluoride, sodium fluoride, potassium fluoride, rubidium fluoride, and cesium fluoride.
Claim 3
Dependent Claim
