Abstract
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.
