Potassium nitrate is a chemical compound with the chemical formula KNO3. A naturally occurring mineral source of nitrogen, KNO3 constitutes a critical oxidizing component of black powder/gunpowder. In the past it was also used for several kinds of burning fuses, including slow matches.Potassium nitrate is also used as a fertilizer, in amateur rocket propellants, and in several fireworks such as smoke bombs. In the process of food preservation, potassium nitrate has been a common ingredient of salted meat since the Middle Ages, but its use has been mostly discontinued due to inconsistent results compared to more modern nitrate and nitrite compounds. Even so, saltpetre is still used in some food applications, such as charcuterie and the brine used to make corned beef. Sodium nitrate (and nitrite) have mostly supplanted potassium nitrate&#**9;s culinary usage, as they are more reliable in preventing bacterial infection than saltpetre. All three give cured salami and corned beef their characteristic pink hue. In the European Union, the compound is referred to as E**2. It is commonly used in manufactured cigarettes to maintain an even burn of the tobacco. As a fertilizer, it is used as a source of nitrogen and potassium, two of the macro nutrients for plants. Potassium nitrate is also the main component (usually about *8%) of tree stump remover, as it accelerates the natural decomposition of the stump. Potassium nitrate is also commonly used in the heat treatment of metals as a solvent in the post-wash. The oxidizing, water solubility and low cost make it an ideal short-term rust inhibitor.
