KNO₃

Potassium nitrate is produced by reacting hot concentrated solution of sodium nitrate or ammonium nitrate with KCl in a double decomposition reaction. Because of differences in solubility, the KNO₃ can be removed from NH₄Cl or NaCl.

KCl + NH₄NO₃ = KNO₃ + NH₄Cl

KCl + NaNO₃ = KNO₃ + NaCl

Small deposits occur around the world however most potassium nitrate is manufactured.

Typical Analysis:

Nitrogen 13%

Potassium 45%

Physical Properties:

• Sizing standard - fine, less than 1mm.

• Bulk density 1.10 - 1.20 t/m3

Use: Potassium nitrate is expensive.

Its main use is in manufacturing liquid fertilizers, as a liquid in its own right, fertigation or as a side dressing fertilizer for vegetable or tree crops.

Restrictions: 

Potassium nitrate is classified as 5.1 hazardous good. It should be stored by itself in a dry place.
