A pyrotechnic material comprising at least one fuel and an oxidizer of ceric ammonium nitrate or a mixture of ceric ammonium nitrate and one or more other oxidizers, and, optionally, sub-micron (i.e., having an average particle size of less than about 1 .mu.m) fumed silica for use as a low-solids ga

A pyrotechnic material comprising at least one fuel and an oxidizer of ceric ammonium nitrate or a mixture of ceric ammonium nitrate and one or more other oxidizers, and, optionally, sub-micron (i.e., having an average particle size of less than about 1 .mu.m) fumed silica for use as a low-solids gas generating composition. When the oxidizer-fuel mixture is within about 4 percent of stoichiometric balance, the pyrotechnic material provides a low solids gas generant less than about 30 percent solids on combustion, and may be formed as pressed pellets, grains, or granules for use in automotive passive restraint systems.

[ We claim:] [1.]1. A pyrotechnic material comprising at least one fuel and a oxidizer comprising ceric ammonium nitrate, wherein the at least one fuel is selected from the group consisting of guanidine nitrate, nitroguanidine, cellulose, cellulose acetate, 5-aminotetrazole, 5-nitrouracil, azo-dicarbonamide, glycidal azide polymer, and mixtures thereof, and the ceric ammonium nitrate is present in an amount of at least about 33 percent by mass, such that the fuel and ceric ammonium nitrate oxidizer have an oxygen balance within about four percent of a theoretical stoichiometric balance.
