Finnish smokeless powder. Smokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to black powder. Because of their similar use, both the original black powder formulation and the smokeless propellant which replaced it are commonly described as gunpowder.
Cordite is a family of smokeless propellants developed and produced in Britain since 1889 to replace black powder as a military firearm propellant. Like modern gunpowder, cordite is classified as a low explosive because of its slow burning rates and consequently low brisance .
Still, black powder remains in use for certain types of firearms, including historical weapons from before the invention of smokeless powder, such as muzzleloaders. Black powder substitutes are propellants designed to provide explosive force similar to that of black powder, primarily for use in such firearms, despite being legally classified as ...
For example, two French battleships, the Iéna and the Liberté, blew up in Toulon harbour, in 1907 and 1911, respectively, with heavy loss of life. By the late 1890s, safer smokeless powders had been developed, including improved and stabilized versions of "Poudre B" (e.g. Poudres BN3F and BPF1), and ballistite and cordite from the late 1880s.
Modern firearm propellants tend to be smokeless powders based on nitrocellulose or similarly nitrated organic compounds, first invented in the late 19th century as a cleaner and better-performing replacement for black powder. Modern smokeless powder may be corned into small spherical balls, or extruded into cylinders or strips with many cross ...
