    • Gas generating compositions and methods for their use are provided. Metal complexes are used as gas generating compositions. These complexes are comprised of a metal cation template, a neutral ligand containing hydrogen and nitrogen, and sufficient oxidizing anion to balance the charge of the complex. The complexes are formulated such that when the complex combusts, nitrogen gas and water vapor is produced. Specific examples of such complexes include metal nitrite ammine, metal nitrate ammine, and metal perchlorate ammine complexes, as well as hydrazine complexes. A binder and co-oxidizer can be combined with the metal complexes to improve crush strength of the gas generating compositions and to permit efficient combustion of the binder. Such gas generating compositions are adaptable for use in gas generating devices, such as automobile air bags.
    • 提供了气体生成组合物及其使用方法。 金属络合物用作气体发生组合物。 这些络合物由金属阳离子模板,含有氢和氮的中性配体以及足够的氧化阴离子组成,以平衡络合物的电荷。 络合物配制成使得当复合物燃烧时,产生氮气和水蒸气。 这种络合物的具体实例包括亚硝酸金属亚胺,金属硝酸铵和金属高氯酸铵氨络合物,以及肼络合物。 可以将粘合剂和辅助氧化剂与金属配合物组合以改善气体发生组合物的压碎强度并允许粘合剂的有效燃烧。 这种气体发生组合物适用于气体发生装置,例如汽车气囊。
