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 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.
In liquid explosives, like nitroglycerin, there may be two detonation velocities, one much higher than the other. The detonation velocity values presented here are typically for the highest practical density which maximizes achievable detonation velocity.
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 ...

Sprengel explosives are a generic class of materials invented by Hermann Sprengel in the 1870s. [1] They consist of stoichiometric mixtures of strong oxidisers and reactive fuels , mixed just prior to use in order to enhance safety.
Gelignite (/ ˈ dʒ ɛ l ɪ ɡ n aɪ t /), also known as blasting gelatin or simply "jelly", is an explosive material consisting of collodion-cotton (a type of nitrocellulose or guncotton) dissolved in either nitroglycerine or nitroglycol and mixed with wood pulp and saltpetre (sodium nitrate or potassium nitrate).
