Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter (or saltpetre outside the US).

Known for centuries for its role in early pyrotechnics, the nitrate ion makes KNO3 a widely used oxidizer with a variety of uses inside and outside pyrotechnics. Properties. Chemical.
4 de abr. de 2023 · Calcium nitrate is a mineral that can be mixed with other high potassium materials to create potassium nitrate, or saltpetre, as it is more commonly known. Saltpetre is an principal ingredient in black gunpowder. Mining saltpetre from the cave was extremely profitable in the early 1800’s, and became even more so with the start of the War of 1812.
The addition of nitrate-based compounds to cured meats is thought to have arisen from the salting of meats contaminated with saltpetre (KNO 3). Saltpetre is a commonly occurring impurity in salt, which enhances its preserving action and produces a red colour in the product (Honikel, 2008).
