Agriculture Grade Potassium Nitrate 500g White Powder Nitrate Of Potash KNO3

Agriculture Grade 99.9% White powder nitrate of potash / KNO3

One of the most useful applications of potassium nitrate is in the production of nitric acid, by adding concentrated sulfuric acid to an aqueous solution of potassium nitrate, yielding nitric acid and potassium sulfate which are separated through fractional distillation.

Potassium nitrate is also used as a fertilizer, in model rocket propellant, and in several fireworks such as smoke bombs, in which a mixture with sugar produces a smoke cloud of 600 times their own volume. The ratio for smoke bombs using sucrose (powdered sugar) and potassium nitrate is 40(C₁₂H₂₂O₁₁):60(KNO₃). It can be used as is, or carefully melted together using a hot plate.

In the process of food preservation, potassium nitrate is a rare ingredient of salted meat, but there are theories indicating that using nitrates in meats can cause cancer. As a preservative it can be known as E252.

Potassium Nitrate is also a main component in stump remover; it accelerates the natural decomposition of the stump. Stump remover is usually about 98% pure KNO₃, and is a common source of KNO₃.

It has also been used in the manufacture of ice cream and can be found in some toothpastes for sensitive teeth. Recently, the use of potassium nitrate in toothpastes for sensitive teeth has increased dramatically, despite the fact that it has not been conclusively shown to help dental hypersensitivity.

A popular misconception is that potassium nitrate is an anaphrodisiac and was added to food in all-male institutions. In fact, potassium nitrate has no such effect in humans.

Although potassium nitrate is used in gunpowder, by itself, potassium nitrate is not combustible or flammable.
