Item Description

Potassium Nitrate

Highly Refined: 99.8% Minimum Purity, Prilled (Small Pellets)

by Duda Energy


Potassium nitrate, also known as salt peter, 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. Used for fertilizer, amateur rocketry, fireworks, smoke bombs & more.

As a stump remover, potassium nitrate will accelerate the rotting of stumps. Simply drill holes into the stump, add some water and potassium nitrate, and the stump will rot more rapidly over time without affecting living vegetation around the stump.
