gunpowder

Gun"pow`der (?), n. (Chem.) A black, granular, explosive substance, consisting of an intimate mechanical mixture of niter?, charcoal?, and sulphur?. It is used in gunnery and blasting. Gunpowder consists of from 70 to 80 per cent of niter?, with 10 to 15 per cent of each of the other ingredients. Its explosive energy is due to the fact that it contains the necessary amount of oxygen for its own combustion, and liberates gases (chiefly nitrogen and carbon dioxide), which occupy a thousand or fifteen hundred times more space than the powder which generated them. Webster's, gunpowder (external link)
