Product Specifications / Features

Potassium Nitrate (NOP)
is highly soluble in water, liquid ammonia and glycerine, but insoluble in anhydrous alcohol and diethyl either. It can't deliquesce in the air. It is mainly applied in compound fertilizer and foliar spray fertilizer for crop and flower. It is mainly applied in TV glass, glass refining agent and motor light glass.

Potassium nitrate has a wide variety of uses, largely as a source of nitrate.
Potassium nitrate is mainly used in fertilizers, as a source of nitrogen and potassium-two of the macro nutrients for plants. When used by
itself, it has an NPK rating of 13-0-44.
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 added to pre-rolled cigarettes to maintain an even burn of the tobacco and is 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, saltpetre is still used in some food applications, such as charcuterie and the brine used to make corned beef. Sodium nitrate (and nitrite) have mostly supplanted potassium nitrate's culinary usage, as they are more reliable in preventing bacterial infection than saltpetre.
Fire extinguishing
Potassium nitrate is the main solid particle component of condensed aerosol fire suppression systems, but when burned, and interacting with the free radicals of a fire's flame, it produces potassium carbonate.
Tree stump removal
Potassium nitrate is the main component (usually about 98%) of tree stump remover, as it accelerates the natural decomposition of the stump by
supplying nitrogen for the fungi attacking the wood of the stump.
Heat treatment of metals
Potassium nitrate is commonly used in the heat treatment of metals as a solvent in the post-wash. The oxidizing, water solubility and low cost make it an ideal short-term rust inhibitor.
Storage for solar energy
Sodium and potassium nitrate salts are stored in molten state with the solar energy collected.
