Applications:
1. 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 13-0-44.
2. 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 added to cigarettes to maintain an even burn of the
tobacco and is used to ensure complete combustion
of paper cartridges for cap and ball revolvers.
3. 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)
have mostly supplanted potassium nitrate's
culinary usage, as they are more reliable in preventing bacterial
infection than saltpetre. All three give cured salami
and corned beef their characteristic pink hue. When used as a food
additive in the European Union, the compound
is referred to as E252; it is also approved for use as a food
additive in the USA and Australia and New Zealand
(where it is listed under its INS number 252).
4. Food preparation
In West African cuisine, potassium nitrate (salt petre) is widely
used as a thickening agent in soups and stews
such as Okra soup and Isi ewu. It is also used to soften food and
reduce cooking time when boiling beans and
tough meat. Salt petre is also an essential ingredient in making
special porridges such as kunun kanwa literally
translated from the Hausa language as 'salt petre porridge'.
5. Pharmacology
Used in some toothpastes for sensitive teeth. Recently, the use of
potassium nitrate in toothpastes for treating
sensitive teeth has increased and it may be an effective treatment.
Used in some toothpastes to relieve asthma symptoms.
Used in Thailand as main ingredient in Kidney Tablets to relieve
the symptoms of cystitis, pyelitis and urethritis.
Used historically to treat asthma.
Combats high blood pressure and was once used as a hypotensive.
6. Other uses
Electrolyte in a salt bridge
Active ingredient of condensed aerosol fire suppression systems.
When burned with the free radicals of a fire's
flame, it produces potassium carbonate.
Component (usually about 98%) of some tree stump removal products.
It accelerates the natural decomposition
of the stump by supplying nitrogen for the fungi attacking the wood
of the stump.
In heat treatment of metals as a medium temperature molten salt
bath, usually in combination with sodium nitrite.
A similar bath is used to produce a durable blue/black finish
typically seen on firearms. Its oxidizing quality, water
solubility, and low cost make it an ideal short-term rust
inhibitor.
To induce flowering of mango trees in the Philippines.
Thermal storage medium in power generation systems. Sodium and
potassium nitrate salts are stored in a
molten state with the solar energy collected by the heliostats at
the Gemasolar Thermo solar Plant. Ternary salts,
with the addition of calcium nitrate or lithium nitrate, have been
found to improve the heat storage capacity in the
molten salts.
Packing and Storage:
Plastic woven bag or kraft paper bag inner with plastic bag in
20/25/50/500/ 1000kg net.
