A gas-generating preparation suitable for being used in an air bag includes ammonium nitrate, a derivative of guanidine and one or more metal carbonates as a deflagration catalyst. By using one or more metal carbonates as a deflagration catalyst, higher burning rates and a lower burning temperature are achieved than if metal oxides such as copper(II) oxide are used as a deflagration catalyst.
[ What is claimed is:] [1.]1. A gas-generating preparation comprising:(a) ammonium nitrate,(b) a derivative of guanidine, wherein said derivative of quanidine is selected from the group of triaminoguanidine azide, quanidine ditetrazole, aminoguanidine ditetrazole, triaminoguanidine nitrate, ammonium-5-nitro aminotetrazole, triaminoguanidine-5-nitroaminotetrazole, and nitroquanidine, and(c) a deflagration catalyst comprising at least one inorganic compound,wherein the preparation comprises from 50 to 75 wt % of ammonium nitrate and the deflagration cataly...
