In 1884, Paul Vieille invented a smokeless powder called Poudre B (short for poudre blanche, white powder, as distinguished from black powder) [7]: 289–292 made from 68.2% insoluble nitrocellulose, 29.8% soluble nitrocellulose gelatinized with ether and 2% paraffin. This was adopted for the Lebel rifle chambered in 8×50mmR Lebel.
[citation needed] Many different mixtures of coating powders and D-gun settings can be used during detonation gun spraying of a material, all of which influence the final surface characteristics of the sprayed coating. Common powder materials used include but are not limited to: alumina-titania, alumina, tungsten carbide-tungsten-chromium ...
It was perfected between 1882 and 1884 at "Laboratoire Central des Poudres et Salpêtres" in Paris, France. Originally called "Poudre V" from the name of the inventor, Paul Vieille, it was arbitrarily renamed "Poudre B" (short for poudre blanche—white powder, as distinguished from black powder) to distract German espionage.

Tetryl is a yellow crystalline solid powder material, practically insoluble in water but soluble in acetone, benzene and other solvents. When tetryl is heated, it first melts, then decomposes and explodes. It burns readily and is more easily detonated than ammonium picrate [3] or TNT, being about as sensitive as picric acid. It is detonated by ...
Antimony trisulfide – ignition promoter; fine powder increases sensitivity, sharpens the boom of salutes; toxic and sensitive to static electricity; [2] emits bright white light, crystals also used as a fuel in glitter compositions and in white comets and pyrotechnic stars. Sensitive to friction and impact; the degree of sensitisation depends ...
Polymer-bonded explosives, also known as Plastic-bonded explosives or simply PBX, are a relatively solid and inflexible explosive form containing a powdered explosive material and a polymer (plastic) binder. These are usually carefully mixed, often with a very thin coating of the polymer onto the powder grains of the explosive material, and ...
Tannerite is a brand of binary explosive targets used for firearms practice and sold in kit form. [1] [2] The targets comprise a combination of oxidizers and a fuel, primarily aluminium powder, that is supplied as two separate components that are mixed by the user.
[26] [27] The XTX8003 extrudable explosive, used in the W68 and W76 nuclear warheads, is a mixture of 80% PETN and 20% of Sylgard 182, a silicone rubber. [28] It is often phlegmatized by addition of 5–40% of wax , or by polymers (producing polymer-bonded explosives ); in this form it is used in some cannon shells up to 30 mm caliber , though ...
