Abstract

Gas generant compositions which include at least one transition metal complex of ethylenediamine 5,5'-bitetrazole and gas generant compositions which include a fuel material of cobalt III nitrate complex with ammonia or water ligands, a burn rate catalyst of copper bis ethylenediamine dinitrate, and an oxidizer of basic copper nitrate are provided to produce or results in compositions having relatively high burn rates. Also provided are corresponding or associated gas generating devices and inflatable vehicle occupant safety restraint systems and methods of gas generation.
