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.
Liquid nitrogen is a compact and readily transported source of dry nitrogen gas, as it does not require pressurization. Further, its ability to maintain temperatures far below the freezing point of water, specific heat of 1040 J ⋅kg −1 ⋅K −1 and heat of vaporization of 200 kJ⋅kg −1 makes it extremely useful in a wide range of ...
The term inert gas is context-dependent because several of the inert gases, including nitrogen and carbon dioxide, can be made to react under certain conditions. [ 1 ] [ 2 ] Purified argon gas is the most commonly used inert gas due to its high natural abundance (78.3% N 2 , 1% Ar in air) [ 3 ] and low relative cost.
Nitrogen and carbon dioxide are unsuitable purge gases in some applications, as these gases may undergo chemical reaction with fine dusts of certain light metals. Because an inert purge gas is used, the purge procedure may (erroneously) be referred to as inerting in everyday language.
Explosive decomposition of organo nitro compounds are redox reactions, wherein both the oxidant (nitro group) and the fuel (hydrocarbon substituent) are bound within the same molecule. The explosion process generates heat by forming highly stable products including molecular nitrogen (N 2), carbon dioxide, and water. The explosive power of this ...
Consider the first triangular diagram below, which shows all possible mixtures of methane, oxygen and nitrogen. Air is a mixture of about 21 volume percent oxygen, and 79 volume percent inerts (nitrogen). Any mixture of methane and air will therefore lie on the straight line between pure methane and pure air – this is shown as the blue air-line.
Nitrogen is a chemical element; it has symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System.
Tovex is a 50/50 aqueous solution of ammonium nitrate and methylammonium nitrate (sometimes also called monomethylamine nitrate, or PR-M), sensitized fuels, and other ingredients including sodium nitrate prills, finely divided (paint-grade) aluminum, finely divided coal, proprietary materials to make some grades cap sensitive, and thickening agents to enhance water resistance and to act as ...
