  2. Activated carbon - Wikipedia

    en.wikipedia.org/wiki/Activated_carbon

    Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed ( activated ) to have small, low-volume pores that greatly increase the surface area [ 1 ] [ 2 ] available for adsorption or chemical reactions . [ 3 ] (

  3. Oxyliquit - Wikipedia

    en.wikipedia.org/wiki/Oxyliquit

    An Oxyliquit, also called liquid air explosive or liquid oxygen explosive, is an explosive material which is a mixture of liquid oxygen (LOX) with a suitable fuel, such as carbon (as lampblack), or an organic chemical (e.g. a mixture of soot and naphthalene), wood meal, or aluminium powder or sponge. It is a class of Sprengel explosives.

  4. Combustibility and flammability - Wikipedia

    en.wikipedia.org/wiki/Combustibility_and...

    The original mass of flammable material and the mass of the oxygen consumed (typically from the surrounding air) equals the mass of the flame products (ash, water, carbon dioxide, and other gases). Lavoisier used the experimental fact that some metals gained mass when they burned to support his ideas (because those chemical reactions capture ...

  5. Powdered activated carbon treatment - Wikipedia

    en.wikipedia.org/wiki/Powdered_activated_carbon...

    The carbon also acts as a "buffer" against the effects of toxic organics in the wastewater. [4] In such a system, biological treatment and carbon adsorption are combined into a single, synergistic treatment step. [3] The result is a system which offers significant cost reduction compared to activated sludge and granular carbon treatment options ...

    en.wikipedia.org/wiki/Pyrotechnic_composition

    Carbon. Charcoal – makes dim gold sparks; Graphite – also used as opacifier in rocket fuels to prevent heat transfer by radiation into lower layers of fuels and avoid the related explosions; Carbon black – produces long lasting fine gold sparks in fireworks, also used as opacifier in rocket fuels; Asphaltum – carbon-based fuel, also ...

  7. Explosive - Wikipedia

    en.wikipedia.org/wiki/Explosive

    High explosives tend to have the oxygen, carbon and hydrogen contained in one organic molecule, and less sensitive explosives like ANFO are combinations of fuel (carbon and hydrogen fuel oil) and ammonium nitrate. A sensitizer such as powdered aluminum may be added to an explosive to increase the energy of the detonation.

  8. Contact explosive - Wikipedia

    en.wikipedia.org/wiki/Contact_explosive

    A contact explosive is a chemical substance that explodes violently when it is exposed to a relatively small amount of energy (e.g. friction, pressure, sound, light). Though different contact explosives have varying amounts of energy sensitivity, they are all much more sensitive

    en.wikipedia.org/wiki/Explosives_shipping...

    Group G: Pyrotechnic substance or article containing a pyrotechnic substance, or article containing both an explosive substance and an illuminating, incendiary, tear-producing or smoke-producing substance (other than a water-activated article or one containing white phosphorus, phosphide or flammable liquid or gel or hypergolic liquid).
