Abstract
Provided herein is a gas-generating composition which forms combustion residues that can be easily captured. The gas-generating composition is composed of an azide of alkali metal or alkaline earth metal, oxidizer, and 0.1 to 10 wt % of one or two kinds of solder glass represented by BaO. SiO.sub.2. PbO. Alkali or B.sub.2 O.sub.3. TiO.sub.2. SiO.sub.2. Na.sub.2 O. The incorporation of solder glass reduces the weight of the filter to capture combustion residues by 5 to 30 wt %.
