Potassium Nitrate Technical Grade Milled

Potassium nitrate milled is a white powder or long needle-like crystals manufactured by Haifa with the chemical name KNO3.  This is very high quality at 99.4-99.7% purity and works perfectly for all applications.  This item has been milled to a fine powder for immediate use in your application.

The most famous use of potassium nitrate milled is probably as the oxidizer in black powder. From the most ancient times until the late 1880s, black powder provided the explosive power for all the world’s firearms.  After that time, small arms and large artillery increasingly began to depend on cordite, a smokeless powder.  Blackpowder remains in use today in black powder rocket motors, but also in combination with other fuels like sugars in “rocket candy”. It is also used in fireworks such as smoke bombs.

KNO3 is also used as fertilizer.   Another possible source is ‘stump remover’, though this is somewhat more expensive and a lot lower quality and purity than this Potassium Nitrate milled.

Alternatively, potassium nitrate milled can be prepared from other chemicals.  For example from nitric acid and potassium carbonate or hydroxide (acid-base reaction), or sodium nitrate and potassium chloride (fractional crystallization).

KNO3 is not particularly dangerous or toxic in small amounts. Ingesting in larger amounts, however, has been linked to cancer, especially in small children.
