Abstract
Abstract Use of 5-oxo-3-nitro-1,2,4-triazole in gunpowder and propellant compositions are disclosed. Such compositions include triple base gunpowders further containing nitrocellulose and a liquid nitric ester such as nitroglycerine. Lowered flame temperatures of the gunpowder and reduced firearm barrel erosion is achieved thereby. The solid propellants include gas-generating compound propellants, less hygroscopic than a propellant contaning ammonium nitrate.
