Because of their similar use, both the original black powder formulation and the smokeless propellant which replaced it are commonly described as gunpowder. The combustion products of smokeless powder are mainly gaseous, compared to around 55% solid products (mostly potassium carbonate , potassium sulfate , and potassium sulfide ) for black ...
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur , charcoal (which is mostly carbon ), and potassium nitrate (saltpeter) .
It is the unit measured by the scales used in handloading; commonly, bullets are measured in increments of one grain, gunpowder in increments of 0.1 grains. [12] There are 7,000 grains in one pound. Black powder substitutes are formulated to be a volume-for-volume equivalent of black powder, not an equivalent mass-for-mass (weight-for-weight).
Poudre B" is made from 68.2% insoluble nitrocellulose, 29.8% soluble nitrocellulose gelatinized with ether and 2% paraffin. "Poudre B" is made up of very small paper-thin flakes that are not white but dark greenish grey in colour. "Poudre B" was first used to load the 8mm Lebel cartridges issued in 1886 for the Lebel rifle.
He built a factory to produce gunpowder near the site of Eleutherian Mills in Newark, Delaware. Today that site has been repurposed as the Hagley Museum and Library. DuPont's first product at the site was blackpowder. DuPont powders were instrumental in helping to build the infrastructure of nations worldwide. [3]
Paul Marie Eugène Vieille (2 September 1854 – 14 January 1934) was a French chemist who invented modern nitrocellulose-based smokeless gunpowder in 1884. He was a graduate of École Polytechnique .
Guncotton was originally made from cotton (as the source of cellulose) but contemporary methods use highly processed cellulose from wood pulp. While guncotton is dangerous to store, the hazards it presents can be minimized by storing it dampened with various liquids, such as alcohol.
This magnified image of H110 illustrates propellant spheres passed between rollers to produce a uniform minimum dimension. Ball propellant (trademarked as Ball Powder by Olin Corporation and marketed as spherical powder by Hodgdon Powder Company [1]) is a form of nitrocellulose used in small arms cartridges.
