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 relative to other kinds of explosives.
chemical energy, such as nitroglycerin or grain dust. pressurized gas, such as a gas cylinder, aerosol can, or boiling liquid expanding vapor explosion. nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239. Explosive materials may be categorized by the speed at which they expand.
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. The combination is relatively stable when subjected to forces less severe than a ...
Pyrophoricity. A substance is pyrophoric (from Greek: πυροφόρος, pyrophoros, 'fire-bearing') if it ignites spontaneously in air at or below 54 °C (129 °F) (for gases) or within 5 minutes after coming into contact with air (for liquids and solids). [1] Examples are organolithium compounds and triethylborane.
Water-reactive substances[1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [3] Notable examples include alkali metals, lithium through caesium, and alkaline earth metals, magnesium through barium. Some water-reactive substances are also ...
Gas explosion. A balloon filled with gaseous hydrogen exploding. A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. [1] In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas, methane, propane, butane.
Methyl nitrate is also the product of the oxidation of some organic compounds in the presence of nitrogen oxides and chlorine, namely chloroethane or di-tert-butyl ether, while also producing nitromethane. [6] Oxidation of nitromethane using nitrogen dioxide in an inert atmosphere can also yield methyl nitrate. [7]
