Application:-

Fertilizer:

Potassium nitrate is mainly used in fertilizers, as a source of nitrogen and potassium – two of the macronutrients for plants. When used by itself, it has an NPK rating of 13-0-45.

Glass Manufacturing:

Oxidizer:

Potassium nitrate is an efficient oxidizer, producing a lilac-colored flame upon burning due to the presence of potassium. It is one of the three components of black powder, along with powdered charcoal (substantially carbon) and sulfur, both of which act as fuels in this composition. As such it is used 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, made with a mixture of sucrose and potassium nitrate. It is also used to ensure complete combustion of paper cartridges for cap and ball revolvers.

Food preservation:

In the process of food preservation, potassium nitrate has been a common ingredient of salted meat since the middle Ages, but its use has been mostly discontinued due to inconsistent results compared to more modern nitrate and nitrite compounds. Even so, saltpeter is still used in some food applications, such as charcuterie and the brine used to make corned beef. Sodium nitrate (and nitrite) has mostly supplanted potassium nitrate's culinary usage, as they are more reliable in preventing bacterial infection than saltpetre..
