Potassium nitrate can be made by combining ammonium nitrate and potassium hydroxide. NH 4 NO 3 + KOH → NH 3 + KNO 3 + H 2 O. An alternative way of producing potassium nitrate without a by-product of ammonia is to combine ammonium nitrate, found in instant ice packs, [30] and potassium chloride, easily obtained as a sodium-free salt substitute.
the nitrate ion, a nitrogen atom bound to three oxygen atoms, (e.g. nitroglycerin, ANFO) the nitrite ion, a nitrogen atom bound to two oxygen atoms [citation needed] Most commercially used explosives include the nitrate ion or the nitro group. II. −N=N−, −N − =N + =N − −
Compositions using nitrate and magnesium metal have been used as photographic flash powders almost since the invention of photography. Potassium nitrate/magnesium flash powder should be mixed and used immediately and not stored due to its tendency of self-ignition. If magnesium is not a very fine powder, it can be passivated with linseed oil or ...
Explosives being prepared for blast fishing. Commercial dynamite or, more commonly, homemade bombs constructed using a glass bottle with layers of powdered potassium nitrate and pebbles or an ammonium nitrate and kerosene mixture are often employed.
The particles need to be very small and fine so that they can be dispersed well throughout the solution. Some salts that are commonly used include: ammonium nitrate, sodium nitrate, sodium perchlorate and potassium chlorate. The sensitivity of the explosive must be increased in order to improve the initiation of the detonation of the explosive.
a nitrate, typically potassium nitrate (KNO 3), which supplies oxygen for the reaction; charcoal, which provides carbon and other fuel for the reaction, simplified as carbon (C); sulfur (S), which, while also serving as a fuel, lowers the temperature required to ignite the mixture, thereby increasing the rate of combustion.
Minol-4: 40% TNT, 36% ammonium nitrate, 4% potassium nitrate and 20% powdered aluminium [2] [1]: M137 The addition of potassium nitrate minimized expansion of Minol, making it more stable to temperature changes than TNT, but didn't solve the expansion problem. Minol IV could still expand and develop cracks after prolonged thermal cycling. A new ...
