Abstract

Abstract Provided is a gas generant composition which is improved in the self-retainabiity of a solid residue and has an excellent combustion speed. The gas generant composition contains a fuel comprising a metal azide or an organic compound, an oxidizing agent, and at least one additive selected from a ceramic whisker or fiber of aluminum borate, potassium titanate, alumina, aluminum oxide, zirconium oxide, and zinc oxide.
