Abstract

PROBLEM TO BE SOLVED: To obtain a composition which has low in combustion temperature, high combustion rate, generates a reduced amount of carbon monoxide and Nox and is excellent in combustion stability by incorporating a bitetrazole compound which is fuel and basic metal nitrate which is an oxidizer into the composition. SOLUTION: The bitetrazole compound has a high content of nitrogen atom in one molecule, low toxicity and the high combustion rate. More specifically, the bitetrazole compound is preferably a bitetrazole ammonium salt. The basic metal nitrate includes basic copper nitrate, etc. The basic metal nitrate is free of a phase transition in a service temperature range and has a high melting point and is, therefore, excellent in thermal stability. A binder is compound with the composition. For example, a carboxymethylcellulosose sodium salt is used. As an embodiment, 0.5 to 10 pts.wt. CMC sodium salt is used with 100 pts.wt. mixture composed of 15 to 35 wt.% eitherazole ammonium salt and 65 to 85 wt.% basic copper nitrate.
