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.

In the Philippines, where the practice has been well-documented, [2] blast fishing was known prior to World War I, as this activity is mentioned by Ernst Jünger in his book Storm of Steel. [3] One 1999 report estimated that some 70,000 fishermen (12% of the Philippines' total fishermen) engaged in the practice.
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.
A saltpetre works or nitrary [1] is a place of production of potassium nitrate or saltpetre used primarily for the manufacture of gunpowder. The saltpeter occurs naturally in certain places like the "Caves of Salnitre" ( Collbató ) known since the Neolithic.
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 ...
The powder has occasionally been used as a synonym for Serpentine powder, which it physically resembles. [2] 'Mill meal' powder is a mixture of potassium nitrate, charcoal and sulfur in the correct proportions (75% potassium nitrate:15% charcoal:10% sulfur) which has been ball-milled to mix it intimately. It is used in the same way as ...
