Abstract:Medieval gunpowder
recipes of potassium nitrate (KNO3), charcoal (C), and
sulfur (S8) were investigated by
bomb calorimetry to determine their enthalpies of combustion and by
differential scanning calorimetry (DSC) to determine their pre-ignition
and propagative ignition enthalpies. Various sample preparation methods
and several additional ingredients were also tested to determine any
effects on the thermodynamic values. Gunpowder recipes were prepared
and used in a replica cannon that was manufactured and ope… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
